Firefox Community Forum

Greetings...

I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions.

Q: Is there a maximum quantity of tabs that a Tab Group can contain?

Q: Is there a maximum quantity of Tab Groups that can be open at the same time?

Q: Does the use of one or more Tab Group negatively affect the performance of my web browser?

Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.)

Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser?

Thank you very much for your feedback! Take care...

Dear Firefox Team,

I hope this message finds you well. I would like to suggest a small but useful enhancement to the Firefox interface that I believe would improve user experience and accessibility.

Currently, in the "Customize Sidebar" section, the available tools are limited to a few items such as AI Chat, Tabs from Other Devices, History, and Bookmarks. I believe it would be very helpful to include "Downloads" as an additional sidebar tool.

This would allow users to quickly access their recent downloads without needing to go through the menu or use shortcuts. It adds convenience and aligns well with the purpose of the sidebar — offering quick access to frequently used features.

Thank you for your time and for continuously improving Firefox. I look forward to seeing future updates! Warm regards, Julabeeb a firefox user, developer, and contributor

i write an email and it automatically goes to the outbox,.... but it never is sent. my sense is that it's trying to send emails via another browser... not firefox and it just locks it up.

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

We want to use Firefox on a locked down system. Using the -kiosk command line argument gets us most of the way there. But they still have access to the devtools when they hit F12. It appears there are ways to disable devtools after the browser has been started. How can we disable the devtools before the browser is opened and without registry changes?

Hello When i download files it has started to put UTF-8 before the name of the file ? Why is that ? Because it doesn't do it if i try it in another browser.

I made sure to sign in and hit sync on my browser prior to moving over to my new computer. I've logged in on my new computer and manually hit the sync button but my passwords and bookmarks are not populating.

Hi there.

The original problem is described here: https://support.mozilla.org/en-US/questions/1472503 ( Also the solution I found.)

Jaws and James seem to have left the building.

This problem first occurred with the update from V 135.0.1 to V 136.0 . Currently on V 136.0.4, and every update has exhibited the same behavior.

I have the same issue with two laptops, running Windows 10. Each has been through a few update cycles, and the "Restart to Update" always fails.

So, I close FF, watch for the Resource Monitor to quiet down, and reopen FF.

When I go through this sequence, I notice that the screen will flash once VERY quickly before opening the home page.

FF seems to function normally otherwise.

Thanks for being there,

My laptop died and I have the SSD in a caddy connected to a spare PC. In order to import logins it looks like I need to convert the existing logins.json file to a csv. Not so keen to upload this to an online site. Tried excel to no avail. I have also attempted to copy and paste with Firefox closed. The file is there but passwords do not load into Firefox. Any suggestions appreciated.

I cannot load Firefox anymore. When I download the program for a reinstall, it only completes about 60% of the install before stopping. Is Google or Microsoft behind this??

Thanks!
