I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!

This afternoon, without any warning, all my mail in every folder could not be displayed. This is the second time this has happened in the last month and a half. I have two mail accounts - one that goes through Yahoo and the other Gmail. No mail is displayed in either account.

When I run Thunderbird in troubleshooting mode, the mail does display. I then disabled the few addons that I use but that didn't make any difference. When not in troubleshooting mode, no mail is displayed.

Of course, there's "troubleshooting information" but that's way too technical for me to get anything out of it.

I've been a Thunderbird user for over 20 years and I would like to keep using it but this performance is discouraging.

What do I need to do to get past this issue? I'm assuming I'll be able to read an email response by using troubleshooting mode.

Thanks.

I have been using the browser extension feedbro and i really enjoyed being able to plop it out of the main browser window and 'add it to the taskbar' but for a couple days this option disappeared. Is there another way to do this? did "add tab to taskbar" get removed for browser extensions? or is this feedbro related? i am unsure how to test whether the button is missing for other browser extensions as well.

added two images showing that the button is gone from feedbro and still there for other tabs/pages

Recent update nuked all my custom containers, and closed every page that was currently open within those containers (pretty devastating bug).

Now, I go to add sites to the new custom containers I made to replace the earlier ones. When I go Manage Containers > pick a custom container > "manage site list ..." and there is no list. Just a blank window.

Since yesterday (15 September 2026), my Microsoft Account has not been working properly. I managed to get round the problem by deleting my cookies. Then the update to version 156 was released, and after that Eule became incompatible. When can we expect an update to make it work again? Thanks.

Installed Firefox on new laptop that has MS Edge, but Firefox is default browser. Downloaded and installed Norton Password Manager to both browsers - no problems with Edge install. Extension downloaded to Firefox, but when trying to log-in to Norton account, Firefox returns error message: Norton Password Manager Sorry, something went wrong. Please try again. Suggestions?

have downloaded firefox because google keeps throwing up adverts continuously. Firefox is doing the same so no better off and cannot use the search bar due to adverts saying I've been hacked
