Firefox Community Forum

I'm using the vertical tabs feature. I also tried enabling the "Expand sidebar on hover" option, which minimizes the side bar, and only expands it when you hover on it.

Issue: I have a lot of open tabs, and I'm usually working with the ones at the bottom of the list. When the bar minimizes the scroll position resets back to the beginning. So, every time I want to select a tab, I have to scroll back down, which makes this feature very hard to use.

Expected behavior: After the vertical bar minimizes, and I hover again, it should keep the scroll position.

Yesterday (5/19), I noticed that Firefox wouldn't load certain websites - specifically, Facebook and my credit union after I tried to login, as well as some commercial websites I use for work, such as Claude.ai. YouTube videos did not play well either - they started buffering after a minute or two. I also noticed that when I was logged into my Google Workspace, apps like Drive and the Calendar had to be refreshed multiple times to get them to fully load - and even then, sometimes that didn't work. Yet other sites would load and function just fine.

After working with Microsoft support yesterday to determine if it was a Windows problem (it doesn't appear to be), I started checking to see if it was a browser issue, especially since I can access everything I need to just fine on Microsoft Edge. I have tried clearing my cache, refreshing Firefox, reinstalling Firefox, and completing a full virus scan on my PC (no issues detected), but nothing has worked and the same problems continue.

Any ideas? (Please note that I have limited tech troubleshooting skills. I am an ordinary user, not a developer.)

Many thanks.

Hello! Today, suddenly, a video player disappeared on the Twitch streaming service (see screenshot), but the stream sound is playing. I tried clearing Firefox data and later reinstalled the browser completely - didn't fix the problem. I installed two versions (115.17.0esr and 115.23.1esr) because I thought the problem was an update. Both versions of the browser have a problem. In another browser, this problem is missing, Twitch is working! Operating system Windows 7 Pro SP1. Can you please tell me how to solve this problem?

I was trying to look at an item on the Costco web page. As you can see from the image "Pop-up being blocked" the size selection is missing. I guessed and allowed pop-ups from Costco.com. As you can see from the image "Pop-up setting allow pop-up" the missing data is visible.

I thought Firefox would prompt if pop-ups were being blocked giving you the option to enable them. Am I wrong? How is a user supposed to know that there is missing data being blocked by Firefox?

I'm using 138.0.4 in MacOS 15.5. When I updated to MacOS 15.5 Firefox only saved one of three windows. The MacOS toolbar at the bottom no longer gives me the option of opening another window, or selecting another window already open. I like the old behavior better.

Hi,

I changed my password in my Mozilla account and now I can no longer sync my firefox for android.

I scan the QR code and on my android screen proceeded normal and asking me to confirm but in my desktop I get an error.

"General application error Something went wrong. Try again later."

I also tried in safe mode with no luck.

What to do now?

MacOS 15.55 on my iMac no longer allows me to Zoom In or Zoom Out after assigning a keyboard shortcut

Usiong m y F18 and F19 keys assigned highlights View on meny but does not zoom anything now - used to work fine some time ago

I have several log in users that pop up when I try to log into web sights. I cant figure out hw to get rid of the wrong ones -- they dot show in saved pass words.. please advise

I logged into my Firefox Sync account last week on a newly re-imaged computer. My old computer is listed under "Connected Services" and for the first few days, when I selected "Sync" from the top right menu, the subsequent menu included the name of the the old computer and the list of tabs. That list of tabs is no longer listed and I haven't been able to find a way to access it. Attached is an image of the menu where the list of tabs was previously listed. Any suggestions are appreciated.

I can not access my email account . I get this message ...

   An error occurred during a connection to login.gmx.com. PR_CONNECT_RESET_ER

I am very used to switching tabs by using the keyboard so I usually do Ctrl+tab and I have it set to recent order (which makes sense to me because most of the time you switch back and forth between two or three tabs) to navigate between tabs. In some recent update, some tabs became unreachable by using this keyboard shortcut, as no more tabs are displayed nor do they appear when you reach the end of the list, forcing me to use the mouse to look for the tab (please see screenshot attached).

I was hoping this had a workaround or if it is a bug I would like to know how to report it.

Thank you!

I have a program which I use exclusively on Firefox and until a few days ago I could open the rtf files which I downloaded on MS Word. Suddenly they won't open. I was told to go to the settings >In Firefox Settings>General, under the “Files and Applications” section, be sure that RTF files are set to “Open in Word” There is no rtf listed there as a file type. Did something get changed recently? This is a massive problem for me. I really hope you can help. Thank you

I am encountering an increasing number of sites that don't work with Firefox but do work with Chrome. I have tried turning off add-ins without success. Is there a way I can easily reset Firefox to its initial state and then return it back.
