Firefox Community Forum

Hi,

I've been using Firefox for years, and suddenly I'm having these strange issues which are forcing me to use another browser while doing schoolwork. They are as follows:

- Discord. When I have Discord open, and then I click another tab, when I go back to Discord the whole screen is black. When I refresh it it's fine, but I have to do this repeatedly each time I go to another tab.

- PDFs. I use Blackboard for my college assignments, and Firefox no longer allows me to open PDFs that teachers post- I just get a blank page when I click on one.

- Black images. Most images show fine, but with some websites (for eg. home depot) the image of the product is black.

I've cleared history, cache, cookies, disabled extensions, and still no dice. Not sure what happened/how to solve this :(

Thanks for any help! zoe

Presently 142.0.1 (64-bit) installed; previous updates/downloads had no problems.

Now, however, going to https://www.firefox.com/en-US/?utm_campaign=SET_DEFAULT_BROWSER and attempt a download results in this (image).

Any solution to this?

Thank you.

Firefox 143.0.3 on Windows 11 24H2. I normally run my browser window full vertical height of the screen (but not maximized). If my PC goes into screen save due to lack of activity, each time I return and it comes out of screen save, the bottom of the Firefox window has risen vertically by about 15-20 pixels, and there is now a gap between the bottom of the FF window and the bottom of the screen. If I go in/out of screen save again, then the gap increases again as the windows shrinks further. The top of the FF window doesn't move, only the bottom.

This problem doesn't happen with the window size of any other app that I use if I size the window the full height of the screen and go in/out of screen save - eg the Thunderbird window remains the full height of the screen.

Any suggestions on a possible cause and how to fix the problem? It isn't just the latest version of FF that has the problem - it was also there with previous versions.

is there a way to prevent HTTP Basic Authentication dialog from stealing focus in about:config? It can be really annoying if a site logs me out randomly while working in another tab. Chromium browsers does not do that

Since installing 143.0.3 (aarch64) on Firefox I can no longer use eBay because the search results page only appears for a few seconds before it skips ahead. (Safari works fine, but it's Safari.) I am using Mac OS Version 15.6.1. I have disabled Enhanced Tracking Protection on the eBay website and cleared the cookies from the eBay website, restarted Firefox, and restarted the computer. There are other solutions offered on the Internet that have sometimes worked over the years for various eBay/Firefox issues, but going down that rabbithole seems likely to be a waste of time. Does anybody have suggestions for the specific issue I'm having?

unable to print. When I click on an AOL email to print, "preparing preview" appears. The email I'm trying to print usually just shows up and I click on number of copies, pages, etc. I need to print. Now, the preparing preview page does not load the email I'm trying to print, and then I get the "firefox has crashed" dialogue box appears.

Hello, recently started using group tabs v143 - very cool!

One thing I noticed is that when I close all the ungrouped tabs I was just using, FF will then open one of the grouped tabs. I assume this was the last grouped tab I used, which may not be today, and not what I want to do right now. Is there a way to have FF not go into a group after that last ungrouped tab was closed - maybe just open a new blank tab or homepage? If not possible now, where do I add this to a feature/setting wishlist? Cheers!

I opened Firefox on one of my computers as usual today but the whole performance changed. Used to go to my home tab and select various news sites to see what was happening. First, when I scroll down the bookmarks, I would hit the "news" and click on it so all the sub items would stay in the scroll, but instead of that, it wanted to open every item as a new tab. When I finally started opening the various news outlets, it opened them in new tabs, it had always opened in the same tab. Then, I couldn't close the various tabs it had opened. I would go to the tab and hit the "X" but it didn't close the tab. I had to use a drop down menu to close a tab. And when in a site, I used the scroll button on the mouse, instead of scrolling, it made the page larger or smaller instead of going up or down. What could make such a change in behavior? I opened up the 'settings' on it and looked at 'tabs' and they were the same as the ones that are on this computer that works as expected. Both computers have it set to open all previous windows and tabs. Both have the same settings for 'tabs' and 'browsing'. I don't get it. Both are version 143.0.3 (64-bit) I have Ubuntu OS.

I had renewed my subscription for MS365 on Tuesday the 30th when I got a popup inviting me to update Firefox to the latest release. I agreed and the download appeared to have worked. However, I soon found I could not access any of the MS365 apps. I restarted and found Firefox had also disappeared. The icons are present in the list of apps but clicking on them gets no response.

I have deleted and reinstalled Firefox and downloaded a new MS365 with no change.

I have Norton online antivirus and the MS365 comes with continuous Defender using Malwarebytes. (I am running down the remaining Norton subscription). I have also used both to do a sweep on each but no problems were found.

I have Outlook which has not been affected.

I am coming to the conclusion that I may need to do a full deletion of both. Can anyone suggest any other way to deal with this?
