After the most recent update, all of my Firefox tabs, bookmarks, and general UI fonts have gotten larger. Is this intended or a bug? There are not options that I know of to reduce the size of the fonts to how it looked previously either.

Since the update to either 140 or 140.0.1 (not sure because I first noticed it in 140.0.1) the marquee does not scroll in on the page when viewed with Firefox, however it does scroll in Edge so it must be a firefox problem. The site is www.maaccordion.com to see the marquee . It also does not scroll in the latest version (at this writing) of 140.0.2

The scrolling has always worked before and it has been on this page (the home page) for quite a few years. Problem only occurred is one of the updates.

Thanks

Firefox stopped working on my computer. Every time I try to open it I get an error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I tried to uninstall and reinstall with no success. Our IT dept tried as well and nothing we have tried has resolved the issue. Thank you for your help.

Whenever I log into QuickBooks Online, I get two popup messages about Firefox/Mozilla wanting me to set up a passkey in Hello Windows. I do not want to do this and cannot figure out how to make it stop asking me. I already have MFA on QBO. This just slows down the login process.

Hoping someone has a solution.

When opening Firefox, the screen turns white before page opens! There is a version that was updated for this issue however,at that time I did not have this issue! After downloading the newer version, I now have this white light issue! I like to mention, my computer never crashed! I believe (134.0.3), was the update that was a fix for the White Screen problem. And, I am using ver-139.0.4 (64 bit) (win. 10-64 bit) I appreciate any help with this issue! Thank you!!! geo (7/6/2025)

I'm on the latest FF 140.0.1 on Linux and I adore tab groups, I'm using it more and more to organize my browser windows. I am using the default (horizontal) tab group layout. Because I have a lot of tabs in the window, I collapse each existing tab group and sort tabs between tab groups.

I can move a tab into an expanded tab group with drag and drop. But I tried dragging and dropping a tab onto a collapsed tab group, even holding it over the collapsed tab group to see if that would work. Nothing seems to register, is it possible?

I would like to move a tab by drag and drop without expanding the collapsed tab group and move the window focus to the next tab. This would save time when I am organizing tabs!

The alternative is to Add a tab to a collapsed tab group, which also expands it and consumes horizontal real estate, forcing me to scroll (further) to return where I was organizing tabs. So I collapse the newly expanded tab group, scroll back to the next tab I want to organize into a different tab group, and repeat but this causes a lot of scrolling navigation to my workflow. It makes complete sense and I really like using menu navigation to add tabs to a specific group because it is discreet and I wish I could move tabs with the same method.

I searched Settings > Tabs and then about:config for browser.tabs.groups.* (and then every preference with tab in it) and couldn't find anything that made sense to me.

Thank you for any help!

When using the picture-in-picture feature, the spacebar is meant to be a keyboard shortcut to pause or continue the video. This is shown on the tooltips for the UI elements in the picture-in-picture feature, and on the keyboard shortcuts in https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_keyboard-shortcuts

However, what actually happens when I press the spacebar key is it instead activates the last UI element to have been clicked on in the picture-in-picture.

For example, if I have last clicked the fullscreen icon to make the picture-in-picture fullscreen, pressing the spacebar will toggle the fullscreen mode, and not pause or continue the video.

Hello, I subscribe to several substacks and, all of sudden, I cannot like, comment, or do anything on substack if I'm using Firefox. None of the buttons respond. I have tried disabling the ad blocker and tracker blocker (I use Badger and Ghostery) but that did not help. If I use a different browser, everything works fine. Any ideas would be very much appreciated!

I cannot access certain sites, especially those with "book" in the address. Tried almost every idea presented on line with Firefox browser on Windows 11. What is the answer? Thanks

I had a whole bunch of open Firefox tabs and tab groups all carefully arranged just the way I wanted, then somehow a couple of tabs got moved to a new window (don't know how that happened, I didn't click the "Move Tab" and "Move To A New Window" menu options), and when I was trying to figure out how to move them back (not possible, apparently) the original window got accidentally closed -- and with it all my tabs and tab groups! When I reopened Firefox they just weren't there. Aagh! Clicking on History just shows the last tabs I accessed, not the full arrangement of groups and the many other tabs I haven't accessed in awhile but want to keep at the ready.

Can I get all that back? Or was relying on Firefox to organize my online work a bad idea?
