Firefox just updated a few minutes ago, and since the update my background in every website I visit is white. Previously my backgrounds were all black due to my Windows 10 "High Contrast Theme" being activated. Well since the update it seems Firefox "ignores" the Windows Theme settings and overrides them with its own. As far as I can tell, there is no way to make websites display with a black background like they did before the update. I hope this gets fixed.

Hello,

I’m using firefox-dev under debian linux and since last updates my cron script that was supposed to open a certain url in firefox at a regular schedule stopped working.

I do export DISPLAY=:0 than run firefox $url and all was fine previously but now I always received a message : “Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.”

You can easily reproduce by running : sudo -u $(whoami) /path/to/firefox-dev/firefox https://www.google.com

Can somebody explain what is checked by firefox and why it consider it is not responding instead of just open my url in a new tab ?

Both drop-down menus (e.g., the drop-down for "Which topic best describes your question?") and popup menus for add-ons in the bookmark bars work inconsistently or not at all. The right-click menu and the 3-bar menu often fail to work on the first few tries, but eventually open. (And in the case of the 3-bar menu, it often opens without certain options, like "Settings," "More tools," and "Help," though these usually appear after waiting a few seconds.) Other menus, like drop-down menus on website or several pop-ups for addons, don't work at all, no matter how many times I try.

The issue isn't solved by starting in Troubleshooting mode (insofar as they can be reproduced -- some things, like the add-on popups, can't be since the add-ons are disabled) or by clearing the cache.

I'm running Firefox Nightly 95.0a1 (2021-10-06) (64-bit) on Arch Linux, though the same issue seems to affect Firefox 93.0.

Thanks very much in advance for any help.

Unable to access "my social security account" on ssa.gov. Of course ssa phone support (and every other website i have issues with) claims Mozilla Firefox Browser is the issue 202110211333

It's been over 2 months I have been attempting contact with them by phone, email, online. I have cleared cache, updated browser, etc. Please assist.

Gratitude's in advance!

fyi: image upload keeps cycling....sending without images.

Sometimes when loading a page, and the page is slow to respond, I will see a strange situation: The page is totally blank (the F12 tool does not display page content). The refresh button is gray (disabled), or sometimes although the refresh button enabled, the url textbox is "about:blank", which means I cannot actually reload the page I want to read. I have to re-navigate to the page through the link in the previous link. I'm not sure whether I got across. I hope the issue can be fixed.

After updating to version 94.0b9, the program began to slow down terribly. This is especially pronounced on YouTube: you select a search, enter a request, open two or three tabs from the proposed one with a possibly useful video ... That's it! You can go to a cafe for coffee and rolls. It became impossible to use the browser.

How to roll back to the previous version of the program?

Sub.: now Firefox Developer Edition 94.0b9 for Linux

Hello,

I am a Web Developer, fixing a website for my client. After the page is cached in Mozilla Firefox the layout breaks, when I clean the cache everything is back to normal. This issue is only present in Mozilla Firefox, I don't have that issue with Google Chrome.

Website URL: https://www.impeccablex.com/ Please see the screenshots attached, you can see the layout before and after.

I have tried almost everything that I could think of, don't know what to try next. Any suggestions?

Thank you in advance! Best Regards, Mario C.

In my "saved addresses" list under the Privacy and Security section of Firefox Settings, there are two addresses of people that have never used my computer. One formerly went to my school, and the other is a stranger. I can think of no way that they could have had access to my account at any time. Are there any other possible explanations for this?

I want to close my firefox account, delete and un-install the Mozilla-Firefow browser and App. then re-install the Firefox browser later. How do i do this? Thanks, I'm on a new MacBookPro laptop with the new M1 chip. Also an iPhone. Help!

I just updated Firefox beta version to 94.0b9 and now I can’t seem to go to some websites. Like “support.mozilla.com” - “accounts.firefox.com” - “addons.mozilla.com” I get an error message “An error occurred during a connection to “support.mozilla.com” PR_END_OF_FILE_ERROR The same thing happens with many other websites that I need to go to. I had taken a screenshot of the message but I can’t upload it! because I can’t go to this website from my Desktop PC, so I am doing this report from my iPhones browser.

Thanks for your help.

In the Find box, sometimes the search skips over my word of interest before I fully type in the word.

I would like to search the old fashioned way in the Find box. Let me completely type my search word and hit Enter before the search commences.

Is this possible?

I do not have the "Search as You Type" option turned on, which really does not apply to the Find box.

Firefox 5 in Mac X OS is VERY slow rendering opacity values from javascrit. It's extremely SLOW in websites which use javascript to "play" with opacity values. As you can see on www.emoure.com (when you open an image from gallery).

I have Lastpass "show logon screen when browser starts" option checked, but it doesn't. Seems I need to add a line to the: When Firefox starts drop-down menu. How?

Hello, At some point I've started to have problems with FF displaying css shadows and fullscreen videos.

1) Here's an example of how css shadows look like on a variety of sites when openned in FF: http://xmages.net/show.php/2871278_css-png.html . Chromium displays the same sites perfectly.

2) There's some kind of a problem with the switching to the fullscreen mode. For example at imdb.com when I click the fullscreen mode button - the video itself starts underneath the browser window and can be switched to with ALT+TAB. Again - Chromium works fine there.
