I downloaded a dark-theme extension but it just wasn't working out (I couldn't read anything on the screen as the black writing turned invisible against the black background. I turned the extension off and deleted it, but even if I open a new window, the dark screen is still there. How do I get rid of it??

Hi, Many times my images won't load on Firefox, but they do on Google chrome. I have disabled all my extensions and it still happens. I even went in and explored this option recommended by firefox: browser.display.document_color_use to the Search box. The preference's value should be set to 1 by default.

Please help! This is so frustrating and I love firefox. Here is an example of what I mean: I log on to https://www.tummee.com/yoga/poses/library to see yoga poses and I get all the stuff but the images of a yoga pose; however, google chrome loads the images. This happens on other sites too. I use a Mac and my Firefox is up to date: 121.0 (64-bit).

I sometimes have a problem connecting to a URL. It does not make any difference which URL. Microsoft Edge has the same problem when this occurs.

I have two network connections. One is via Ethernet and one via WiFi. I generally don't connect the WiFi since I am sitting next to my router. Yesterday, when this occurred, I connected the WiFi and everything worked. I thought it had something to do with my WiFi, but today when it failed I tried the same thing and the problem continued.

I ran the Microsoft troubleshooter and it displayed that I was connected to the Internet.

When this occurs I can ping my router successfully, but I cannot connect to my router via Firefox or Microsoft Edge.

Today I rebooted my router, even though other devices do not have a problem connecting to the Internet, and when the boot was completed everything worked. When I rebooted the router my PC indicated that it did not have a connection and when it was able to access the router initially it indicated that I did not have a connection to the Internet. When my PC indicated it had an Internet connection Firefox functioned correctly.

I have a UPS which has my router, modem, and desktop PC connected. We have had power failures and either my PC is turned off or I turn it off. My router and modem continue to function and we can access the internet via tablets or cell phones. I was wondering if the power failure somehow could have affected my network provider and I needed to reset my router so that it could establish a new connection to the modem. Don't know if this makes any sense or not.

I have Microsoft Office 2021 which is Microsoft's perpetual license version of Office 365. I use Outlook in Microsoft Office 2021. What surprised me is that when this is going on Outlook will function correctly.

Is there anything I can access in Firefox that can help me determine what is going on, or do you have any suggestions?

I use mozilla firefox as my main web browser, and youtube sometimes does sometimes doesn't load (picture below). This happens only on firefox. Every other website works fine tho.

When I use the url calculator, the number will display as expected, e.g. if I type 900-756.07 Firefox displays 143.93 in the url. However, when I try to copy that number, the length of the numbers decimal places changes substantially, e.g. 143.93 turns in 143.92999999999995.

Is there a way to prevent it changing the result?

Just today a web based TV show has stopped playing, the circle spins for a moment (as if it was loading) the circle then just vanishes and nothing plays.

I am running Win 11, I have successfully had the video play in Edge and Brave.

Firefox however is being stubborn and refuses to play

Firefox opened with a set of questions just now. I did what was appropriate then it was like FF reset. All of my home page shortcut boxes were gone and I want them back. FF/Mozilla sent a verification code to my email. I typed the url for my gmail account and FF did nothing. A page came up with the url and it was blank. The tab had an icon grayed out and the page was blank. So I had to go to Edge to sign in to my gmail to get the code. I am at work. I do not have time to search through a plethora of articles trying to find how to get my shortcuts back. Why did they go away in the first place. This is maddening. I've used FF for years and it has always been simple. I just need an answer to what should be a simple question.

Thanks in advance for your help.

I was able to get rid of remembered user id data in Chrome (delete site data) with no problems, but have tried all I can find in Firefox with no luck. Please tell me how to do it. There is no saved login data in Firefox and deleting site data does not help. Thanks, John.

For a while now, several bank credit card sites are not working correctly when I use my Firefox browser. It did in the past and I didn't have any problems but lately I'm having these problems happening on sites I've used for years. If I use another browser it will work with no problem. In fact after talking with some of the support people at some of the sites that won't work, the suggest trying another browser which works fine. I'm talking like American Express' website which I use a lot. There are other sites other than credit cards that are not working correctly and again, their support agent will tell me to use another browser. I have tried different remedies like clearing cache, history, etc. I only use few addons like AdBlock which helps to cut down on trackers and information gathers. I have set my preferences to clear out my history and cookies. I have used Firefox for so many years without problems and with the same addons without any problems. So what is causing this to happen? I do enjoy using Firefox but if I have to keep changing over to another browser so sites will work, then maybe it's time for me to stop using Firefox.

Artifacts on webpages when hardware acceleration is enabled. Disabling hw acceleration removes artifacts, but degrades performance of browser significantly. Using hw acceleration in Chrome has no artifacts. The error is not in the hardware or driver, but in the Mozilla software. By searching on this topic on Google, it's a common error in Firefox.

The last version where artifacts where not present was: pp_name: firefox build_date: 2020-01-15 build_file: C:\Users\tulle\.mozilla\mozregression\persist\2020-01-15--mozilla-central--firefox-74.0a1.en-US.win64.zip build_type: nightly build_url: https://archive.mozilla.org/pub/firefox/nightly/2020/01/2020-01-15-21-36-21-mozilla-central/firefox-74.0a1.en-US.win64.zip changeset: c35bb210b8ae793c844bd94c1848d246bf601293 repo_name: mozilla-central repo_url: https://hg.mozilla.org/mozilla-central

I am an experienced Firefox Add-On user.

I have installed Firefox on a new build Windows (10) computer. Only 4 of my 8 installed Add-Ons will show on the Task Bar

This is not a problem on my two other Windows machines that share the same Mozilla account for Bookmarks & Passwords. (Other machines are also 4K displays).

I have uninstalled then reinstalled Firefox several times on the new machine, nothing seems to work.

I suspect there is a simple fix, but it eludes me.

Suggestions?

I use firefox for browse internet, but after some time firefox start randomly crash. After some investigation i noticed in resource monitor that one of firefox processes has commit 100% of my computer memory. After some time that process reach maximum memory that my computer has and firefox crashed. But windows still was open (frozen with no content and windows XP border).

None of my installed Add-Ons will open. This occurred after running in "Refresh Mode" to correct a different problem.

The prior problem involved not opening bookmarks in a new tab even though the config:about entry was set correctly.

Is it possible there is a config:about entry that prevents any add-on from running?

I use Firefox to access Audible. Audible can be accessed through Amazon.ca.

1. I can no longer reach Audible using Amazon.ca.

2. ALSO, I can no longer access Audible from the internet (using Firefox).

In both cases it says "GAH ... your tab just crashed. "restore this tab" is available to click on, however, in both these instances, it does not work Thank you for any help you may be able to impart.

The removal of the download status bar at the bottom of the browser is a major UI failure and this feature needs to be returned.

I spent 30 minutes attempting to download/extract a settings file from an Addon until I noticed that Firefox was silently downloading it to my Downloads folder without any notification that it had started or completed.

The download bar was a known solution for this; The bar itself did not obscure the current webpage, provided immediate feedback on download initiation, progress, and completion. Provided quick access to open the file(s) or find options about the file(s), and the download bar could be dismissed quickly if the vertical page space was required/desired.

The hidden download tray is a horrible design idea, makes it difficult to see if your downloads have started successfully, when they have completed, and how to access them. Additionally, the introduction of 'hint' popups to support this feature actively obscure the webpage you're viewing, making them dramatically worse than the download bar, which left the page completely usable and only required a few pixels of height at the bottom.

This is a major design flaw.
