Developer no longer involved Rated 3 out of 5 stars

I was told in an email:
"Sorry, I don't have any time to work on Vertical Tabs. It's on GitHub (, feel free to fork it, or work with some of the other folks who have forked it and are improving it. I'm really not involved anymore at this point."

I have no idea how to use GitHub!

Buggy with FF32+ Rated 1 out of 5 stars

Moved to Tree Style Tabs extension, which works correctly with almost same functionality. Chrome also has vertical tabs in dev version

Rated 5 out of 5 stars

Best vertical tab add-on out there. Simple and lightweight, the only issue is the recent Firefox upgrade that broke vertical tabs on start-up. The work-around, to disable and enable the add-on, works.

Has anyone reached out to the author yet on this?

Does not work correctly in the FF 32.02 Rated 4 out of 5 stars

If after running FF32.02 make disabling/re-enabling this add only then it works. Need to fix it. Please.

Sill works on FF32, but not properly. Rated 3 out of 5 stars

The whole disabling/re-enabling thing works for version 32, but still has problems for me. Moving them doesn't work and sometimes tabs cannot be closed. This still needs a fix.

VT in FF v32.02 Rated 3 out of 5 stars

I am running FF v32.02 and it is a pain in the butt getting VT working the way I want. I click on the FF menu/add-ons, click on VT options, click on "tabs on right", close FF, open FF, click on the FF menu/add-ons, click on VT disable, click on enable and VT works the way it used to. Unfortunately, I cannot do without right handed VT and must put up with it.

Still works on Firefox 32 Rated 5 out of 5 stars

I tried what Eliza did below (disable then re-enable the add-on) and it still works on Firefox 32!

This app is one of the main reasons I use Firefox and not Chrome -- thanks philiKON!

This is a really great addon but with version 32 it no longer works correctly. Will it be fixed soon, I really like having vertical tabs. Thanks

Rated 5 out of 5 stars

fantastic, thanks a lot, however it's broken now with Firefox 32.0.1 on Windows 7 64 bits... please fix it, I can't live without!

Rated 4 out of 5 stars

Dear philiKON,
I have noted that the Horizontal tabs issue is mostly with 64 bit browsers- like Mozilla Firefox 32 on Mac or Waterfox 32 on windows 64 bit OS like windows 8/8.1. I hope you are able to resolve it asap. Thanks again.

Simply great app Rated 5 out of 5 stars

I absolutely HATE horizontal apps! This app restores my sanity. Although with this recent problem (32) I have learned how to tolerate Horizontal apps, so if this app ever goes away I can continue, but I won't like it.

So thank you philiKON!

Quick Fix for Vertical Tabs not Displaying Vertically Rated 4 out of 5 stars

I too updated to Firefox 32 and am experiencing problems. My tabs display horizontally, but when I go into my tools dropdown, choose add-ons, then choose Vertical Tabs, I disable it, then enable it and then the tabs appear vertically.

However, my other issue is that some of my tabs won't close when I click on the close x. It's just acting strange.

I have used this for years, and don't want to give it up! Please fix asap.

Great add on, but needs fix for firefox 32 update. Rated 4 out of 5 stars

I love this addon and like the other recent reviews, it was going well untill the bleedin firefox 32 update. I'm dissabling any further updates to firefox and hope that vertical tabs can get fixed soon.
it's hard for addon developers to keep up with firefox when they're springing updates every two minutes.

Broke in Firefox 32 :( :( Rated 4 out of 5 stars

Ok i'm here to complain ;)
But i have been using this for a long time. I like it.
But it doesnt work in Firefox v32 (which just auto-updated).
I am a vertical space person in a wide screen world ;(
So i have my windows 7 icons on the left.
Then i have this set to tabs on the right.
That way when i mouse over the w7 firefox icon, and get the preview, i can see all the tabs. If FF tabs are on top or on left, then the W7 preview covers tabs and i can't see what's there.

But, with FF32 what happens is that the tabs are moved from top to right (or left by default) but instead of stacking 'vertically' (like the name says) they stack horizontally.

Yes, that's correct. I have a large pane on the right and at the very top of that pane all my tabs are listed horizontally. Gets crowded quick.

philiKON, we love ur addon; can u pls fix?


Rated 5 out of 5 stars

I love this, it can hold a lot of often visiting websites.
Unfortunately the update to Firefox 32 crashes the sidebar, it doesn't work.
Even restoring the "old" Design with another app doesn't helped. Hope it will get fixed soon.
