Firefox Community Forum

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

Periodically (in the nature of 2 to 5 days) my Firefox will remove a selected setting that autofills my passwords to various familiar sites. Specifically, the box labeled "Ask to save passwords", is the box that will 'uncheck' itself. I want it to stay checked. How do I make it stay checked?

I have exported my theme made in Firefox Color (love it) - both xpi and zip. The theme has been working for 2 weeks. I just want to reinstall it to check, and eliminate Firefox starting with "default" and then loading my theme. I also have no backup if I had a computer malfunction.

I'm not sure how it can be "corrupt" since I'm looking at it working right now. I exported using your site and your buttons - but when I try to install it says "unable to install because it's corrupt."

Updated recently from (I believe) 138.04 to 139.0.1, and immediately noticed that the size of font (and icons) had changed in the folders I have in the bookmark toolbar, that is they are much smaller and thus also less space between. Why this, and is it possible to change the size, without changing something else?

It's possible that many don't have folders in the toolbar and thus don't notice, but I have 2-3 apart from bookmarks.

I remember a change many versions ago that increased the space between entries in the bookmark menu, and also in the bookmark toolbar folders. That was too much and I found a setting [in config] that could be changed to decrease the space back then. (I haven't looked for that solution now, probably have some doc somewhere, and won't bother searching since this is different. Same with this case; I did some quick initial search but found next to nothing and older. BTW, this is one of the downsides of changes like these and similar; the day you have too move to another OS version, i.e. reinstall everything you also have to keep documentation of all these little changes, apart from all the other things you'll have to export or save.)

Firefox is asking me for my primary password, but I've never set one up. If I try to turn off using the primary password, it says I have to enter the current primary password to do so. Firefox only started asking me for a primary password earlier today. I tried to log into my Mozilla account, but it said I didn't have one. I've created one now, but still can't get past the screen asking for my primary password. My email address is alexduckett1@yahoo.com

Your new update deleted all of my favorite bookmarks. Many of which were for business and special research. How do I recover them? They are beyond price. Their loss is a complete catastrophe!

Firefox updated this morning on my desktop (not this device) and still mid-afternoon my tabs are taking minutes to load and the LastPass extension is still grayed out, i.e. inoperable. This happens to some extent EVERY TIME IT UPDATES but this is the worst. Went out for a long lunch and still nothing works. I have things to do and have no browser! Windows 11 Home fully updated Dell Inspiron 3670 i5-8400. I’m *this close* to moving to an alternate browser but really like Mozilla and don’t want to. What can I do to fix this when it happens? I used to run Windows Update troubleshooter and it worked a lot of the time (no idea why) but it’s gone.

I am getting this screen effect when I start trying to play.

Since posting this, I noticed that the dulling effect starts when I click on the screen, and if I then double-click the brightness reverts to normal! So I tried with a wired mouse to see if that was the problem, but no difference so I can rule out the mouse. I'm starting to suspect a browser hijacker or some malware. Only getting the effect on this computer, with only this Firefox browser. My main PC is working normally in the same programme. Very weird.

my 32bit Thunderbird has just updated to 139.0 and the message pane has changed an I hate the look/layout . how can I get it back to how it looked before the update easily thanks

EDIT: - I sorted it. The update put it to 'Cards View' - I went into settings and switched it to ' Table View' and its back to normal now - phew!

Since I restarted my MacBookPro this morning, this pop up message continues to pop up. Apple said it couldn't see any other avenue except for the use of the FireFox browser. How do I make it go away?

Over an hour trying to sync one desktop to another desktop, your methods, your synchronization are like trying to escape from Alcatraz. And you know what happened to Alcatraz? IT CLOSED. So exasperated I could kick my dog. Nah, I LIKE my dog.
