Hi, I set up the vertical tabs and I like them. However they're very unstable and so is the tab sidebar. The expand on hover feature only works for a short time. Then the x to close a tab disappears and the sidebar gets stuck open or closed. If it gets stuck open, it covers the settings and AI and history sidebars so I need to close it manually to use them. Yesterday I lost 3 of my 6 pinned tabs. After closing and opening FF, they were just gone.

Also my tab groups will suddenly disappear. This started in the previous version and still happens, and I lose the sites I had collected. Plus FF has been very slow to load.

So yesterday I gave up and reverted to horizontal tabs. Like magic FF suddenly worked perfectly and very fast. I'm not enough of a techie to have any idea of what is causing what and would really appreciate any advice.

I have a pdf document with live hyperlinks to websites. However, when I click on them, they open in Edge and not my default browser Firefox. Any suggestions? Have set default browser to Firefox and default PDF to Acrobat reader.

I am getting a Secure Connection Failed error on every webpage I try to visit. Even if a page manages to load it will revert back to the Error code: PR_END_OF_FILE_ERROR if I refresh. Other browsers are working fine. I tried troubleshoot mode and it's the same. I tried uninstall/reinstall, desktop restart and still the same. I haven't changed any settings on my mac.

Hi, I wanted to reduce height of tabs and remove borders in file userChrome.css.

So far this works for height, but was wanting to know if a negative value can be used to reduce further, Also tried some code to remove radius but it didn't work. Remove radius for selected tab and also hover on tab.

/* REDUCE HEIGHT OF TABS (VERTICAL TABS) */ .tabbrowser-tab { min-height: var(--tab-min-height) !important; max-height: var(--tab-min-height) !important; }

I don't think any of the above topics relate to my question.

When I am typing an email (AOL), I type for awhile and then all of a sudden, the cursor just disappears. I have to point my mouse again and click to get it back. Then I type again, and all of a sudden it again disappears. I have read articles, etc. but nothing seems to help it. What is the problem and how do I fix it? If I switch to a different browser there is no problem; only in Firefox.

Thanks, Kathy

Hi all. I'm experiencing a frustrating video playback issue in Firefox on my Mac. Whenever I move my cursor, the video becomes noticeably blurry until I stop moving it. Then it takes a second and returns to normal sharpness. This problem is exclusive to Firefox and doesn't happen in other browsers. One interesting quirk is that it seems like the lower the video resolution is, the more noticeable the blur appears.

This video on Reddit shows my issue perfectly: https://www.reddit.com/r/mac/comments/qbecrh/m1_has_problem_when_playing_video_and_moving/

I've already tried several common fixes, including disabling hardware acceleration and other graphics settings such as tinkering with gfx.webrender, but nothing has resolved it. I'm hoping someone on the forums might know if this is a known bug or if there's a solution I haven't found yet.

Specs: MacBook Pro w/ M1 Max (2021) macOS Sonoma 14.1.2 Firefox 143.0 (aarch64) ... but the issue has been going on for years so I doubt that the macOS or Firefox version has anything to do with it.

I'm at a total loss here and would be immensely grateful for any help.

"If there is a problem with how this image is displayed, view it in a browser" Always goes to Microsoft edge by default. How can I make Firefox the default for viewing email messages in my browser?

I really like the possibility of unloading tabs but still have them visible as I need to be able to backtrack some searches which are many levels deep. One thing I have discovered however, is if the tabs are grouped, you cannot unload them and that poses a problem for me as I have many many tabs that live in various groups across my tab bar. Is there any way of unloading these tabs while they reside in a group or is there a workaround I have not thought of yet?

Cheers and thanks everyone for your support and suggestions ....

I seem to have installed the YouTube webapp on Firefox when I clicked 'add tab to taskbar' that's new in 143. It shows up as recently added program on Windows. When I go to find the origin it leads to Firefox.exe. I can't find a way to uninstall through the browser or on Windows. Does anyone know how?

The scrollbar slider isn't displaying correctly. If I grab the screen, zoom in, and look very carefully, it is possible to see that the slider is a very slightly different darker shade of grey to the rest of the scrollbar, but it's almost impossible to see, so something is clearly not working properly here. The scrollbar should be highly visible as it's the most often-clicked control of the entire browser.

As in if not minimized just the once, the taskbar doesn't unhide when I move the cursor all the way to the bottom.

It happened earlier this year, an update fixed it, and it came back some updates ago.

Is there anything to configure in the about:config to alleviate this issue?

Many thanks!!

bold text I thought I had messed up my Firefox home screen somehow, when I deleted cookies and data (I am 84 and not techy, and not keen on changes!), but now I see that an update has done it. I want my old home screen back, with the 'previous tabs' feature restored instead of the 8 bookmarks that now occupy that space, most of which I rarely use. How can this be done, please?

 I'm using Windows 11

iOS 26.1 on an iPhone SE; Google Maps 25.47.0. Links to apps don't open in-app. If I click a Google Maps link, it sends me to the App Store. If I click a link to Instagram, it sends me to the App Store. But I already have those apps! How do I make it work like it used to?

Hi! Firefox now has two profile managers. The old one can be used so that I can open two Firefox instances with different desktop files on Linux with the "-P and --no-remote" command line flags. Is this also possible with the new profile manager in Firefox that came with version 138, which is similar to Chrome's? With Chrome this can be done with the "--profile-directory" command line flag. Can't find information about this. /Regards
