It says on https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_keyboard-shortcuts that the hotkey to toggle `PiP is CTRL Shift ]`. When I play a video it shows the PiP button, but the hotkey doesn't work. The other PiP keys like seeking and volume work. I'm on Fedora 41 with KDE 6.3.3 & Wayland.

If I display (e.g.) Nepal in Google maps, initially the Nepali names appear beneath the Latin alphabet names, but only for a split second. They are then overwritten with unicode block icons. Some scripts work (e.g. Cyrillic, Chinese, Japanese, Armenian), but most south Asian scripts do this weird "works for a split second" rendering.

I'm running 128.8.0esr (64-bit) on Debian 12.

This problem does NOT occur in Safe Mode!

In Normal mode, I disabled all plugins and extensions, but the rendering still breaks.

Any ideas?

The same page renders properly in Chrome 134.0.6998.88

Is this a bug or config problem?

Occasionally, FF (Linux desktop) starts using a lot of memory. I kill tabs (sometimes it is OK to kill YouTube or X, sometimes not)

Eventually it starts impacting the system using so much memory. I terminate the FF instance. Often. More often than not. There is a separate task still running and I get the "Firefox is still running" when I try to restart. I then kill the remaining FF task via the OS or the process monitor. Then FF restarts.

Is this an issue with addons (I am running very few - uBlock Orign, and Privacy Badger and Cookie AutoDelete. Are the only ones active most of the time) Or is it an actual bug with garbage collection, and tasks getting away? Or is it an OS issue?

snap version seems to have problem thought this might help. I am a software developer.

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

The visual and audio notifications for incoming emails being posted to the inbox of gmail under Mozillia Firefox do not function correctly when ran on a Linux Mint operating system computer.

I can get the visual notifications to work as long as the Firefox is open but once that session is closed the visual notifications are no longer issued, i.e. the setting to issue those notifications are not being saved upon closing of the browser.

I can get the audio notifications to work on a sporadic basis. I go into the settings on gmail and choose one of the audio sound notification choices and it works a few times when income emails are received into the inbox, but then just stops even if the current firefox/gmail session is still open.

My theory is that those firefox/gmail settings are not getting preserved/saved in proper manner to be available for subsequent sessions of firefox/gmail because firefox/gmail does not understand the FILE STRUCTURES of Linux Mint Mate so that those settings can be properly preserved for use by subsequent sessions of firefox/gmail.

Please consider fixing this.

Thanks.

I updated firefox just yesterday or earlier today idk and the right click menu is so long with multiples of the same and they DO NoThInG! Linux Mint 22 Cin. 6.8.0-55 Generic Kernel

After the last Linux upgrade to 36.0.2 the password or user name hot links only work once. The first time the link is gray and will activate. The second time I try and use this feature the link is not gray and will not activate.

Every time this happens I have to close Firefox and reopen it. Then I get one more shot at auto loading a password before it stops working.

I have a Linux PC where, when I right-click, I see shortcut letters in the context menu (the one that appears when you right-click). So, if I want to inspect an element, I right-click on it and press Q, and the inspector opens right away. This saves me time from navigating through the menu. However, on my other MacOS PC with Firefox, it doesn't do the same. I've searched for solutions but haven't found any.

Was prompted for various system updates including apps(Firefox). Performance has been very sluggish. At some points, it feels like I'm browsing on dialup. I have a 1GB connection from my ISP.

Not sure if this is a Firefox issue or in conjunction with the other system updates.

Here are the dpkg/apt logs for update:

2025-03-19 12:33:16 configure firefox:amd64 136.0.2~build1 <none> 2025-03-19 12:33:16 status unpacked firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status half-configured firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status installed firefox:amd64 136.0.2~build1

The problem is that when I tried opening gmail in my ubuntu, it is stuck at loading page, but other browsers like edge can open it without any problem (on the same system).

I tried every thing I can in the support forum of gmail/mozilla/others, but it's still stuck at loading.

That's all.

I access google drive through Mozilla Firefox and also zip file or other file download but since 1 to 2 weeks i faced issue to download files especially js file.How can I solve this?

When I attempt to use Firefox autofill for address/credit card/etc, Linux will prompt for Root password. After entering root password, everything freezes. I have no access to mouse or keyboard and my entire OS become unresponsive. Besides the hangup, my firefox tabs randomly crash as well with the following bug tag: https://crash-stats.mozilla.org/report/index/3020d645-af46-4821-bbfc-e4d680250213. I don't know if the two are related, but both eventually lead my my OS freezing with only hard power down. Every time I try to use autofill, it freezes my OS. I can keep replicating the issue.
