Firefox Support Forum

Hey there. To get straight to the point, whenever I am watching a YouTube video on Firefox in full screen, every so often the screen goes black then slowly fades back in. I have no idea how to fix this issues and it is not my computer that is causing it (doesn't happen on other browsers, my computer was tested for a variety of problems and nothing was wrong, etc). I have also looked through Firefox Reddit help pages and the support articles on the Firefox support website but have found nothing to help. Any suggestions or help would be much appreciated! Thank you :)

So yesterday I downloaded a bunch of files to mod a game. This warning appeared and since then it's been popping up every time I start the browser. I have cleared all cookies related to the relevant sites. I have removed the warning about unwanted and uncommon software. I would rather not clear all my cookies and data to resolve this, so looking for other suggestions first. I don't mind digging through files or code to make it happen.

I can’t seem to open any Word files in Firefox. Doesn’t matter if it’s a new file or an old one, it just won’t open. What’s weird is that it takes me to a OneDrive page saying the file doesn’t exist or isn’t available. But when I switch to Google Chrome, everything works fine.

I use the Kindle Cloud Reader (https://read.amazon.com/kindle-library) to access and read ebooks in my Amazon Kindle library. Since the latest Firefox update something is preventing my ebooks from opening correctly. The ebooks open, but only a single page appears and none of the navigation controls load.

Amazon support suggested trying a different browser. I loaded the Edge browser and had no problems opening my ebooks. I prefer to use the Firefox browser so I hope you can fix this issue.

The last Firefox update, 126.0 (64bit), that was installed 2 days ago has caused various website's commentary or forums to not be displayed. For example, Yahoo finance page, attempting to read the "community" section of a particular stock such as Walmart (WMT) nothing is displayed. This happens also on news websites that allow commentary. Google Chrome does display commentary but I don't like using Google.

This is not the first time commentary has not being displayed after an update. Happened a couple of times last year.

The desktop pc is running Windows 11, version 23H2.

Thanks, Frank

I recently had to reinstall Windows, as a result of a hard drive issue. This involved reinstalling Firefox from scratch.

As such I had browser.sessionstore.resume_from_crash set to false, but browser.sessionstore.max_resumed_crashes was still set to its default value of 1. The combination resulted in a browser restore after a crash...

This would seem to imply that browser.sessionstore.resume_from_crash has either been deprecated (though that is not mentioned in the knowledgebase article), or it is not being correctly interrogated in the code. Unless I am missing something, and I do not want to go thru the entire config to see what else I might need to set...

If I am reading this wrong, please let me know if there are other entries that need to change from default. In the event of a crash, I want the browser to start with my home pages, NOT restore.

Currently on FF 125.0.3 (64-bit) - and yes, I know there is an update waiting for me to restart my browser yet again...

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

How do I delete all traces of FireFox. I did the "remove program" but when I reinstall it is remembering that I once had Firefox installed so that tells me it has NOT fully removed all traces of Firefox. So please tell me how to remove everything. I keep getting errors that I don't get when I use other browsers, so there is some sort of issue with Firefox so I absolutely need to remove EVERYTHING. There must be some hidden files that the uninstall program is NOT finding. I need all profiles, files, bookmarks etc GONE!!!!! so I can do a new install. PS The REFRESH did not fix my issues so please don't offer that as a potential solution.

All of a sudden, Firefox (125.0.3), running on Windows 11, is not delivering any sound at all on websites which have music or people speaking. The TOR browser does deliver the sound on those same websites.

How do block a fake recurring alert?

Hi, not sure the best place to ask, but it's been an ongoing issue since 2022. I kind of believe a shift in Intel has caused some of these issues, but probably not important (and I've already contacted them and did not get anywhere) at the moment.

Essentially, having Firefox running crashes the Intel UHD Graphics system, typically it is the UHD 620, but I believe I have some systems with a UHD 630. On Windows, I get a blank screen for 1.5 seconds, on macOS it crashes the entire Mac. I...I have a hard time wrapping my head around the fact I'm the only one with the issue and has occurred on multiple computers over a period of 18 months. The systems in question include the following:

Dell Optiplex 5040 MT - Fixed by putting a GTX 1650 in its 16x slot. Dell Optiplex 5060 MFF Dell Latitude 7290 Dell Latitude 7490 MSI GF63 (9th generation revision) MacBook Air 2020 w/ Intel i3 under macOS.

The thing is, with the exception of the MacBook, PCs don't report any issues apart from a "Hardware Failure" within the Reliability Monitor and the aforementioned screen shutoff. With World of Warcraft I'm able to reproduce the issue consistently under both DX11 and DX9, but Firefox not so much. I do see it occurring only on YouTube videos on the MacBook and is more common to occur on PC, but I have also had it happen on normal browsing.

I can turn off hardware acceleration and have done so, but I do wonder how much of an impact it will make on power efficiency on say, battery power. Would be something that should be fixed and I would like to put effort into getting it resolved, but I have no idea where to start. All drivers are up to date, Intel Boost is disabled (and I wonder if having it set as so causes this, though the MSI has no such BIOS setting) and it only occurs on Windows PCs with Windows 11.

Thanks for reading.

I'm considering switching to Firefox for my primary browser BUT once I log in to AOL to check my mail, the print is tiny and cut off top and bottom of each letter. This is not a new problem, but I'm using Firefox more now and still have to use another browser OR another device to read my email. I am attaching a screen capture of what it looks like.

Hello Forum,

I keep my shift schedule as a bookmark on my toolbar for quick reference. It's rather small 554x670.

Is there a url modifier to make it load at the %200 i usually look at it at?

http://page.com/image.jpeg:zoomx or something like that?

Thanks Community.

once every week or two, private browsing shows up in history. it is not cleared when i close all private windows. the rest of the time it works as it's supposed to. any suggestions are welcome. thank you. running 125.0.3 on mac ventura 13.6.6

There are some pop-ups I cannot stop.

Naturally, I have clicked “stop pop-ups” in the Privacy and Security section of Firefox Settings. That has worked but not quite. I keep getting some “via l-itineraire.com”. That’s a website I used during a recent holiday in France.

So I installed Block Site.

That has an option called “Block a new host name”. I entered “l-itineraire.com.” and clicked Add. This has had no effect. The pop-ups still arrive from them.

I know there’s an option to open the website and get into the Firefox toolbar, but that’s defeated me. Yes I managed to get to click Menu, but not beyond. Anyway, that should not be necessary – after all I’ve clicked no pop-ups.
