Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

I'm having real problems with the pop up "find text" box that appears at the bottom of my Macbook Pro when I try to enter data on web pages since I updated Firefox a few weeks ago. I can find articles on disabling this feature for PCs, but nothing for Macs. Please help !

Bonjour, Sur mon P.C, il est impossible d'avoir ma position, votre logiciel me situe à Laval, alors que j'habite Saint-Etienne, du coup, il m'est impossible de regarder aucun site marchand style brico-dépôt ou autre puisqu'il me situe au mauvais endroit. Auriez-vous une solution à me proposer, d'avance merci.

I've exactly the same problem as described here. https://support.mozilla.org/de/questions/1442833

This is a privacy problem, because most of the time when I open a website like google.com, I don't want to be logged in so the website can identify me. I only keep a container tab for such a website around, so I can open it if I explicitly want to be logged in.

Cannot open my cart nor add items to my cart on https://www.guitarcenter.com/Black-Friday-Electric-Guitar-Deals.gc?filters=categories.lvl0:Guitars&icid=LP12589#paginationTopAnchor I can take that same URL and immediately open it using Google Chrome.

When I try to load "Comments" I get this message:

Failed loading comments! Please try again...

Trying again doesn't help.

This is a fairly recent problem

Thanks for your help.

I'm building a website from scratch and its going great. I just tried to implement a CSP and it worked except for one small section of my website that allows a user to upload an image and that image is supposed to be displayed back to the user. Anyways long story short the CSP blocked me so I tried to whitelist data: and it still didn't work. defeated I removed the CSP from Nginx to work on it later but when I went to try and test again I get this error. ``` Content-Security-Policy: The page’s settings blocked the loading of a resource (img-src) at data:image/webp;base64,UklGRqbeAABXRUJQV… because it violates the following directive: “default-src 'self'” ``` I have confirmed with Curl and by inspecting the network tab that there is no CSP included in the headers anymore. I have restarted Firefox, created a new Firefox profile, and cleared my cache to the end of time and yet still the error persists. I don't know where or how Firefox is storing website headers but they persists and also apparently work between profiles an implication I'm not going to delve into here. If someone could point me to the file where the headers are stored so I can delete it that would be wonderful.

Hello,

I'm facing an issue where my microphone does not work in Google Meet when using Firefox, even though I’ve granted all necessary permissions. This problem is specific to Firefox, as the microphone works perfectly fine in Google Chrome.

I prefer using Firefox because of its convenient screenshot features, but this microphone issue has caused major inconvenience during important meetings.

Kindly help me resolve this issue.

Thank you.

Hello,

how can i disable firefox usage hints like "Try tab groups for less clutter, more focus"?. It opens up if i open up a certain amount of tabs. Is there anything i can disable in about:config?

Thank you.

I host a website, and don't want browsers (particularly Firefox) offering modified versions to others. Is there a header or something I can set webserver-side to disallow Firefox from offering the option?

This doesn't work:

add_header Cache-Control "no-store, no-transform, public" always;

Hello,

In multi-window browser sessions on Linux, the "Recently closed tabs" menu shows a list of URLs relevant to the parent (aka current) window, and that is both perfectly logical and highly useful. It makes it a lot easier to find that specific URL you're looking for, if not only because it increases the chance that it hasn't yet been flushed out of the recently-closed list.

I have a very distinct memory that this was the case on Mac too for the URLs showed by this menu when accessed via the "hamburger menu". I'm positive that I accessed the function via the hamburger menu rather than the faster way via the menubar for that very reason. And I just realised that it's no longer possible starting with at least v143.

With the Mac's global menu bar it would stand to reason that it presents lists that are "global" to the session, but I see no good *usability* reason that would justify *not* using window-specific lists under the hamburger menu.

One could of course argue that it's confusing and a "burden" to the user that s/he would need to remember in which window the looked-for tab once lived. But that argument would apply to all platforms, and this is supposed to be about *recently* closed tabs and one has to assume that the majority of users have no issue remembering in which window they have (or had!) a given tab open. (And that otherwise they'd be using a singe window, probably maximised to occupy the entire screen ;) ).

The offline package download speed is too slow and sometimes fails. I hope it can be provided separately, like interface language packs, just as Debian has separate interface language packs.

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

This one is puzzling to me: On a website with login, whenever I click on an link to a pdf, a new tab opens (my normal setting) and immediately crashes (not my normal setting ;)). However, everything is fine elsewhere on the web, even on the same site in the sections without login. Here are some observations that may or may not be connected to this:

• If I right-click and open in new tab/window/download, everything is fine
• When I return to the tab where I clicked the link, the page reloads - independent of whether I did anything in the crashed tab
• the site-admins were not able to reproduce the problem, also it seems fine for other users
• the problem persists in troubleshooting mode, also manually disabeling extension did nothing, emptying cache etc. also nothing.

It is not like this is making me switch browsers (although no crashes in edge), but it bothers me to have no idea why this is happening. :) Maybe someone here feels the same? Thank you for reading either way!

Hello,

After recent macOS updates, it appears that Firefox would get stuck when trying to access passkeys stored in macOS's passwords or keychain apps. I run into this issue with both the following two combinations of Firefox versions and macOS

144.0.2 on macOS 26.0 Tahoe

140.4.0esr (aarch64) on macOS 15.7 Sequoia

Any insight is appreciated!
