Download Cleaner Lite

Rated 5 out of 5 stars

Does what it claims to do and works as expected, so there's no reason not to rate it 5 stars.

bitwarden - Free Password Manager

I must admit, I'm really impressed! Rated 5 out of 5 stars

It's very simple, lightning fast, it's open source, you can choose to run your own server if you like and a premium membership is very affordable. It's basically the LastPass, that LastPass should have become but never was.

Okay, it misses some nice features of LastPass (e.g. no secure notes yet), but these are already work in progress (just like native desktop clients) and once done, it will make LastPass look like an overpriced amateur project.

I always was a big fan of LastPass, I'm still a paying customer, but with every release getting slower and more buggy than the release before, their inability to migrate to WebExtensions on time and their absolutely unjustified increase in price (pay twice the money for half the service as their customer support is not worth a penny recently), I think I'll switch to this service. And, of course, I will get a premium membership again, as it's absolutely worth the price.

Save Image to Downloads

Works okay Rated 4 out of 5 stars

There's just two things that would need improvement:

1. When I click the Firefox icon top left on this page and choose "Save image as...", it will suggest "firefox.png" as filename. When I use this add-on on the image, it is saved as "firefox.png?b=95020746-59df8772" which the system will not recognize as PNG.

2. The menu entry is named "Save Image to Downloads...", but "..." indicates, that this action requires further user interaction and usually opens a dialog. This is exactly what this add-on is not doing (it shows no dialog, it does not require further user interaction), so there should not be "..." at the end.

LastPass Password Manager

Was the best, but new owners run it down Rated 2 out of 5 stars

I can only repeat what other users have already said here:

* Development is slow (still no sign of Fx 57+ support)
* What LP releases has usually beta quality at best
* Bugs really everywhere (from UI to functionality)
* Speed is poor and getting worse and worse.
* Autofill works randomly at best.
* Bug reports get the reply "we have reported the issue to our R&D and cannot promise any fix" and that's it (translation: Oh, we love to take your money and no, you cannot request anything in return for it, just give us your money)

I've been a long term user, using LP for years, used it when hardly anyone has ever heard of it and I'm a paying customer for years, too, the question is only for how long I'm willing to accept twice the price for not even half the service.

AdBlocker Ultimate

The add one works, the list management sucks Rated 3 out of 5 stars

Offers plenty of filter lists, but they are poorly named, many have duplicate names (but are in fact different lists!), no detailed descriptions what these lists actually really filter or who is managing them or where these lists come from, no way to see what's actually on these lists or how many entries a list has. There is also no way to add your own custom lists, something pretty much every adblocker out there offers (you could only copy/paste their content into the custom rules field). The whole list management is basically crap.

Compare that to uBlock Origin, where lists have much better naming, are sorted into meaningful categories, where you can see their origin and also their content, as well as their size. Also you can add your own list URLs. uBlock Origin also seems much faster and much more powerful, albeit the UI is somewhat more ugly.

Oh, and bug reports and feature requests seem to be generally ignored. I don't even know if this addon is really actively developed.

I give it three stars as with the right lists selected, the addon does work quite okay and filters most adds as promised, but I see far better adblockers available here.

LastPass Password Manager

IMHO still the best Rated 5 out of 5 stars

If you need a password manager solution that will work across all platforms (including smart phones), all OSes, all browsers and that is more than affordable (many users can use it for free and even a premium account is very affordable compared to competitor prices), LP is for you. Storing passwords on servers is always risky, but using poor passwords or the same passwords everywhere is much, much, much more risky today!

Regarding all the comments about 4.x: 4.x is still not stable, it's an alpha version. So it has bugs, it may not always work correctly, it may be slow, functionality may be missing, it may fail completely if there is a browser update. That's what alpha means. Seriously, how can you install an alpha version and then make complains like that and give poor ratings? That's also why there is no autoupdate to 4.x Users have to decide themselves if they want to test alpha versions. Once 4.x is considered stable enough to replace 3.x, there will be an autoupdate for sure. Right now you are not missing anything if you stay with 3.x (the biggest changes are the new UI look so far).

Self-Destructing Cookies

Awesome! Rated 5 out of 5 stars

I was always asking myself why there's only "allow forever" and "allow for session" in Firefox, yet no "allow while page is open". This addon adds exactly that missing functionality and it works like a charm.

Youtube and more – Easy Video Downloader

It's very simple and it actually works Rated 5 out of 5 stars

It has no complicated settings (actually it has no settings at all), no complicated interface or menus. You just open a page with a video, start playing the video (sometimes you don't even have to start it), click the green icon (should have turned green to indicate that it found a video) and click the video you want to download. The downloads dialog opens, a nice name is suggested already (even if the real file has just a number or other cryptographic name), click OK and the download starts. That's it. It works where other video downloaders fail (they don't even see a video) and contrary to these, it can even be installed w/o browser restart. All thumbs up!

Enforce Encryption

Finally an Add-On that works Rated 5 out of 5 stars

Contrary to Force-TLS which doesn't work at all since Fx 36 (you can add domains to the list, but that's all you can do, they will still open at HTTP), this add-on really works and does what it is supposed to do.

UPDATE (October 9, 2015):
Now that the UI has been improved (see comment below) my only real point of criticism has vanished, so this add-on now deserves 5 stars.

Still broken in 38.0.1 Rated 1 out of 5 stars

Adding a site to the list has no effect, site still opens with HTTP. Checking the checkbox on the Permissions tab of the Page Info will also add the side to the list, but already when closing and reopening then Page Info (without reloading the page) the checkbox isn't set anymore (yet the site is still on the list).

And it's not Firefox that is broken here. When installing Enforce Encryption, opening the page with HTTPS and checking the force checkbox, the page is also added to the list in Force-TLS, but now it will open with HTTPS (as desired) and now the checkbox on the Permissions tab of the Page Info is checked when I open it, so this add-on does it right.

Foundstone HTML5 Local Storage Explorer

Rated 2 out of 5 stars

UI is very limited, cannot be sorted or filtered, window cannot even be resized, refresh button does nothing (have to close and re-open window to see updates) and it fails to show "session data" (if you force all cookies to be session cookies, HTML5 DOM Storage data is also only kept for the current session and that session data never appears in the window). All in all I cannot recommend this addon.

Keychain Services Integration

A must have for Mac all users! Rated 5 out of 5 stars

This plugin works as expected. There is nothing to configure, just install it and your passwords are stored to keychain and read from keychain instead of the internal storage or Firefox or Thunderbird.

For Mac users it just "feels natural" that applications store their passwords via the Keychain Service API. I was always disappointed that Firefox had no keychain support built-in; but for Thunderbird this was actually a showstopper! This addon is the *ONLY* reason why I started using Thunderbird again on the Mac! Finally I don't have to enter a Master Password each time Thunderbird is started, because w/o a Master Password your passwords are not really protected at all (every app with access to your profile folder can easily access and decrypt your e-mail passwords). Now all my mail passwords are securely stored in a keychain.

And I want to thank the author of this addon for implementing the Keychain Service API correctly! Some Mac developers, sometimes even Apple themselves, fail to use this API correctly. They always think the user will never have more than one keychain and this one keychain is always named "login". This is of course a major fail. The user may have hundreds of keychains, some may be shared with other users, some may not, and he is free to move items between them as he pleases. Sometimes, when I move a password from one keychain to another one, some apps fail to find it. Of course apps should always search all keychains in the Keychain List for their items, picking the first match found (as keychains are searched in a specific order that can also be controlled by the user) and they should always add new items to whatever keychain is the default keychain (which may not be named "login"). Actually both happens automatically if one doesn't tell Keychain Service otherwise. Also items should always be updated in place; some apps delete the old item first and then create a new one, but that can cause items to move from their current keychain back to the default keychain, it also causes a loss of access control rules, both is of course undesired. As far as I can see, this addon works exactly as it should :-)

Download Panel Tweaks

Almost Perfect Rated 4 out of 5 stars

A very handy add-on which I can only recommend. I really like the way how it helps to compact the lists, change the number of items displayed, the time remaining format and the mouse over behavior.

What I miss is the functionality of "Download Cleaner":

It would integrate perfectly into this add-on.

Download Statusbar

Rated 5 out of 5 stars

I really love this addon. It's the most important addon of all my addons, since downloading files without that addon is simply no fun. Unfortunately it isn't working with Firefox 26, but I'm pretty sure that can be fixed :-)


Rated 5 out of 5 stars

I really love the new interface! ^_^ Having items sorted by day is really a neat feature and being able to see from what feed they are is very useful. Also the annoying bug that "Unread" comes up empty (until you switch to something else and back again) has finally been fixed.

I have no idea what lilacle is talking about, though, hitting F (or the icon on top) still toggles between preview and head line view.

Almost Perfect Rated 4 out of 5 stars

Very useful extension to get rid of those stupid icons on the tab bar (something Lightning should offer by in its preferences IMHO); however, there is one tiny bug. When you add these buttons now to the mail toolbar, they work without any issues, however, on my Mac, they don't get "highlighted" when you click them (usually, when you click a toolbar button and keep the mouse pressed, it is darkened until you release the button again; this works with all items except those provided by this extension).

Keychain Services Integration

Rated 5 out of 5 stars

Now that I switched to LastPass, I won't need this extension any longer, but it is great that such an extension exists! Where I would still need such an extension is for Thunderbird, since there is no LastPass plugin for Thunderbird unfortunately :-( This extension works great, as far as I tested it :-)

Rated 4 out of 5 stars

It works perfectly for me (tested with English and German dictionary installed) and it switches really fast, even though the code looks rather expensive. I see some room for improvements (still not worth 5 stars), but it's pretty good.

Tree Style Tab

Rated 4 out of 5 stars

Brilliant idea, works great also, I'd give you 5 stars, but it has some display issues on Mac. Neither does the (semi) transparent mode work correctly, nor does any of the themes really fit perfectly to the native Mac theme.

This review is for a previous version of the add-on (0.7.2009031701). 

Proto for Mac OS X

Direction okay, but still a long way Rated 4 out of 5 stars

Okay, as has been said here before, there are some really nasty issues. One issue is that the close button (X) is wrong side (on Mac we use to have it in the upper left, also for windows, not upper right, as Windows OS has).

Another issue is that the preferences tool bar is... well, I'm not sure what it is or what it is supposed to immitate, but it's ugly (sorry I have to say that).

Regarding what Nibbling Hell Goat wrote, I disagree with the tabs being attached to the wrong side. They are exactly like Safari does it and nobody ever complained about it there.

But I agree with Billau, Fission was one of my most favorite plugins ever; being unable to use it with that theme is very, very bad.
