My Reviews

Classic Theme Restorer (Customize UI)

If I had not found this add-on, I think I'd have to abandon Firefox. Rated 5 out of 5 stars

Thanks, man, thanks! And it also helps add-ons work again which do not work properly anymore with the n-th overhaul of design (eg Pocket).

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

Automatic dictionary switching

Really helpful Rated 5 out of 5 stars

Working fine, it really helps me a lot, having correspondents in several countries speaking different languages.

I'm just wondering where the data is stored? For trouble-shooting... you won't need it in everyday life. And if there was some indicator (flag, or just text) in the status bar, that would be lovely. Just some suggestion for future versions.

EDIT 2015-01-10: Thanks for the reply! I found the data in the user preferences (file pref.js or preferences extensions.automatic_dictionary.* in config editor). As for the little status bar flag I dreamt about, I contacted him directly and got the answer that he prefers to keep the add-on as simple as possible (and I do agree).

Styles Tuner

Simple and efficient Rated 4 out of 5 stars

This will color certain elements on any web page according to their HTML tags (eg "li.row), it's rather easy and does not require any further knowledge of CSS (just a rough understanding of what HTML tags are may be useful).

Yet it will not work with any site, for example with the feed reader - I have not yet figured out when the extension will be invoked. But it works fine with, which should be using javascript to add text to the web site, too.

Block Content (img,css,js,...)

Thanks, you saved me! Rated 5 out of 5 stars

I don't know why more and more websites are putting videos, they may think it's funny, I think it's annoying, and I don't see why a browser should support this. Thanks to mdsy, I can now browse without being disturbed.

Bookmark Quick Mover

Rated 5 out of 5 stars

An absolute necessity, missing in standard Firefox.

Scroll Highlight

Nice feature but no configuration possible Rated 4 out of 5 stars

It's a really nice feature to help you to continue reading after scrolling down a page.

Yet it would be nice to be able to configure the line (opacity, time to show), which is not possible yet.

EmailPicky 4

Rated 5 out of 5 stars

Works fine for me, even on IMAP account, and offers quite a lot of options (only TO, FROM, CC etc).


Great idea - but with side-effects Rated 4 out of 5 stars

The context menu in itself is shortened as expected, five stars for this, I was waiting for such an extension for so long.

But there are side-effects... for example, the menu of the ScreenGrab extensions becomes "shortened" and thus completely invisible.

Tab Grenade

Nothing special - closes all tabs and creates a list Rated 3 out of 5 stars

Will close all tabs and create a page from where you can re-open them. No history or form data maintained. Opened tabs will not be removed from the list.

I'd rather recommend Read-it-later, bootstack, or add-ons to bookmark all tabs.

Pinboard IncSearch

Useful and fast (but hidden in tools menu) Rated 4 out of 5 stars

Seems to download all pinboard bookmarks and performs a rather fast search on them. Great !

The only drawback is that is not really integrated into Firefox (e.g. as a sidebar) but that you have to run it from the tools menu (I was struggling a little while before I found that out).


No more thread view by default Rated 5 out of 5 stars

Finally a way to set the normal list view as default again.


Rated 5 out of 5 stars

Great! And now you can even specify in which directory the data is stored so it works seamlessly with synchronisation software like Dropbox :-)

This review is for a previous version of the add-on (4.0.1). 

Date Picker/Calendar

Nice, handy, does what it says. Rated 5 out of 5 stars

For date format options, look at

Sort Tabs by URL

Great, accessible via Tool Menu now Rated 5 out of 5 stars

Sorting by URL seems to be the most natural way to cope with a huge number of tabs opened. Simple to use (thanks to entry in tools menu).

Phrase Highlighter

Best highlighter so far Rated 5 out of 5 stars

Simple but efficient highlighter, I tried many, this seems to be the best by far. Work boundaries (\b) work fine in regular expressions. Would love to see this on Thunderbird, too.

This review is for a previous version of the add-on (1.8).  This user has a previous review of this add-on.

Phrase Highlighter

Best highlighter so far Rated 5 out of 5 stars

Probably the best (but still simple) highlighter around.Regular expressions seem to work fine even though I've got an issue with word boundary (\b).Would love to see this for Thunderbird, too.

This review is for a previous version of the add-on (1.8). 

Color Folders

Great Rated 5 out of 5 stars

There used to be a problem with virtual folders (search folders) but there's where I need the colors most. This seems to be repaired now and it's fantastic for me now.

This review is for a previous version of the add-on (1.0). 


Rated 4 out of 5 stars

Great! I may have wished to have a bit more options about what to see and maybe to toggle between standard and compact header, but so far it's really improving the experience with Thunderbird on smaller screens... Except that it seems that the compact header defines a minimum width which will make my window (under ubuntu), when maximized, reach over the end of my screen (on a tiny netbook) - or is there some other addon incompatibility??

This review is for a previous version of the add-on (2.0.7). 

Thunderbird Conversations

Revolutionises message handling Rated 4 out of 5 stars

Great, it really shows the whole thread in an overview and helps me a lot!!

I'm giving it only four stars because some things may still be improved:
- show contact picture
- allow to send the reply later (it's sending immediately if you use fast reply)
- some issues with text size (even though it's okay for me now, I had some issues before on other computers)

That said, let's not forget that it revolutionizes (replaces) the way the messages are shown so some incompatibilities (eg when using an addin to display contact photos) will be inevitable.

This review is for a previous version of the add-on (2.6.3). 

Folder Levels

Great but not for virtual folders Rated 4 out of 5 stars

The idea is great and it makes the whole folder structure much more readable. Alas, it only seems to work for real folders (remote or local), but not for virtual (search) folders.
