Firefox Community Forum

items dragged to overflow menu pop back out, will not stay there - dunno how to fix this.

Hate the "puzzle piece." Involuntarily upgraded to 115.25.0esr and it lost all my bookmarks, addons, history. How do I know which profile was the most recent, before the update added a new profile? How do I find my addons from the previous version? history?

Recently clicked to update to the next version of Firefox. Then I get the message "Restart to Update Firefox." I restart Firefox but the message is still there when I click Help > About Firefox. It would appear that the update did not happen for some reason. Do I need to re-install Firefox to get around this problem?

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!

I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?

I recently encountered an issue when attempting to login to The Coventry Building Society website using Firefox (desktop PC & Windows 10):- https://www.coventrybuildingsociety.co.uk/ It failed to display the page used to enter the one time passcode used for two factor authentication.

After looking on some forums I discovered this is because 'Strict' tracking protection was enabled. If I change to 'Custom' and uncheck 'Tracking Content' then things work as expected.

I also read on a forum that you can leave tracking protection set to 'Strict' but enter the URL for the problem website under 'Enhanced Tracking Protection -> Manage Exceptions'. I tried entering 'https://www.coventrybuildingsociety.co.uk/' Initially this appeared to work. However, when I tried it again the following day, the page failed to load as before. I had to change back from 'Strict' to 'Custom' and uncheck 'Tracking Content' once again. It's as if the exception URL is ignored in 'Strict' mode.

Am I doing something wrong or is this how it is supposed to work? Do I need to click on the shield icon (to the left of the padlock icon) and turn off 'Enhanced Tracking Protection' every time I visit the website?

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

Why can't I sync computer bookmarks to iPhone? I can't get my iPhone to show up on list of connected devices. I've tried everything in Help. I have a Mozilla Account. Running 135.0.1

From the Firefox Start Page on my iPhone (running 18.3.1) . . . the menu in the bottom right hand corner does not give me the option to "Sync and Save Data". This is a roadblock for me! I'm not a computer genius but I'm not completely ignorant. I should be able to do this! https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-02-28-15-53-59-c3d764.png Help please!

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

This is pretty shady Mozilla.

When disabling only one setting: "Allow Firefox to install and run studies" it wrecks this site whether logging is or continuing as guest:

https://appointment.questdiagnostics.com/schedule-appointment/as-personal-information

Even after logging in and everything running normal, disabling the studies run by Mozilla and a quick refresh breaks the functionality of the page. All cookies were accepted and the sharing of location was allowed. On a fresh, first run, wide open Firefox people. Literally, the only change that was made was unchecking that one box. In disbelief, i tested it over and over.

Why would disabling a telemetry setting, something that should be optional, cause this to happen? Seriously, what could possibly be the reason. I'd love to hear it.

This was the final nail in the coffin to me and this is since the 0.9x days.

Hello,

Since the latest update of Firefox (version 135.0.1) when writing an e-mail the lines keep dropping down automatically at random intervals.

The e-mail host we are using is Polaris Mail, which is through our website provider.

To make sure it wasn't an issue with polaris mail, i have logged into our emails through microsoft edge and they have worked perfectly fine.

I have attached a picture for reference.

Kind regards

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.

Firefox closed the browser for an automatic update two days ago, and when it came up back after the update all my open windows and tabs simply disappeared. History tab was reset to a blank page, there was no trace of anything. I tried the access through 'Menu / History / Recently closed windows' or '.../ Recently closed tabs' and they were both blank, empty, zero, nada ... This is the first time it happens to me, and I'm surprised and disappointed that such a predictable and basic bug shows up on an update.

I have a couple dozen tabs I use for task f-ups, it' unproductive and annoying to get them all back up to work. If this happens again I doubt I keep using Firefox as my preferred browser.

1. Anybody else suffering the same issue?
2. Is there a cure for the problem?
