Firefox Support Forum

Running Ubuntu Linux in version 80.01.

Problem: Since Updating to Firefox 76, a strange problem occurs. All dark colors and context menu backgrounds become transparent. When having a window open behind the Firefox window, it will show through in all areas with dark colors (through images, text, menu's). This problem proves an issue, as I had to change my main desktop background to a solid black one to make Firefox usable, even so, I cannot use the context menus while on a website with a white background.

Solutions I have attempted: Changing browser themes/system themes Reverting all cosmetic changes Disabling all privacy add-ons Reverting all modified settings Even a fresh install using a different (default) profile did not work

What semi-works Booting in safe mode does fix the issue but the fresh install did not.

My question is: Does safe mode do additional modification to the browser other than reverting user modified settings? Basically, does safe mode mimic a fresh installation and if it does do additional changes, is it possible mimic the cosmetic changes that it does for normal browsing?

Since several version of Firefox, I'm unable to use the menu of Firefox when in full screen as it shows itself outside of screen. As I understand it, the origin of the windows seems not correct, as the arrow on the top, which should be under the mouse pointer, is at the opposite. (See the picture attached, it's probably best explained that way).

I've tried to launch Firefox in safe mode, but It didn't change anything.

For the past few weeks ebay has stopped loading in firefox . looks like html, no pictures just lists all the words I contacted ebay but no one else has reported anything. Does anyone else have an issue.?

I'm using Firefox NIGHTLY - 82.0a1 (2020-09-06)

Although I have 4 dictionaries installed (not language pack, dictionaries) and can access them when writing in most webpages, I cannot use them, or even see the "Languages" sub menu when right-clicking on Office 365 and Gmail through the web browser. I can see misspelled words, as they are underlined in red, but it doesn't give any correct spelling when I right-click on them also.

I am running Firefox 80.0.1 (64-bit) on a Windows 10 computer. When I recently opened my LastPass vault I can see a dialog box asking for me to grant LastPass permission to access website info so the extension can fill forms. There is an Accept and Decline button. Unfortunately, this dialog window and the buttons appear to be floating behind the entries in my vault and can not be selected or clicked.

I'm hoping this can be fixed, and also wonder if this type of error appears on other sites with dialog windows.

Hi there,

I am using Firefox 80.0.1 in Ubuntu 18.04, although I have also encountered the following problem in previous versions of Firefox.

I have Firefox configured to always ask me where to download files.

Whenever I try to download a file, Firefox always suggests as destination directory a temporary directory, such as:

/run/user/1000/doc/643c8d42

It doesn't matter if I choose a different location, next time I try to save a file Firefox always defaults to a similar temp directory.

I have tried fiddling with the variables browser.download variables, such as browser.download.LastDir, but it does not fix the problem.

Any suggestions, please? Thanks in advance.

Firefox is disappearing from screen and taskbar, when other items are opened but the audio continues to play, and has to be ended from the task manager to continue otherwise opening Firefox opens a new sessions without previously open tabs and audio continues to play. happened after newest update to 80.0.1

I was having issues with video play back where some times the sound would just go crazy and the video would freeze, so I uninstalled and reinstalled firefox and now for some reason if I switch from speakers to my blutooth headset I get no video playback from firefox to the blutooth headset. it continues to play thru the speakers even though everything else on my pc plays thru the blutooth headset. so I tried a complete clean install and the video issue seems to be fixed but I still do not get video played in firefox to play thru my headset. anyone got any ideas? is it possibly a permission setting in firefox? any help woul;d be appreciated because I am at a complete loss. thanks in advance for your time.

When I switch to my Work VPN, Firefox fails to switch to the new connection automatically. I have set the Proxy to use the System proxy settings. Edge/Chrome don't have this issue. Is there a way to make Firefox to switch connections without the need to restart it?

I only have 4gb of RAM. Firefox uses over 700mb of them which leaves me with less than 10% of free RAM. In safe mode the free ram goes from 7% to 20%. Disabling all addons etc drops free ram from 7% to 11%.

Chrome uses 500mb less RAM. How can I reduce Firefox's use of RAM
