Hi,

My Mozilla Firefox Web developer tool keeps autonomously toggling on/off in any Firefox window/tab..

Its as-if I'm repeatedly hitting Ctrl-Shft-I (which brings up the web developer tool in the bottom 1/4 of the browser).

I've checked all Setting, turned off all hardware acceleration as suggested for similar flickering problem (which wasn't on anyway).

I use Norton 360 Security Software but have Norton Safe Web disabled. The only active Extensions are Firefox Multi-Container and Firefox Sideview.

Its not doing it at the moment, but I'm not sure exactly what triggers it and expect it to happen again.

Last time it happened I was browsing Amazon. Hitting Ctrl-Shift-I only makes is turn off until start scrolling again, etc.

I don't think its virus related, because I use Norton 360, and Task manager "Performance Tab" show the computer is generally very mellow.

Please help, as I love Firefox, but this problem can drive one crazy.

Thanks Larry Zdanis

I have a PC that cannot access the Internet. Using a thumb drive, I was going to download Firefox then load it onto the PC. Do you think this will work and if so, how do I put Firefox on the thumb drive (be specific - step by step). Thank you

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.

After loading the pop-up blocker extension I cannot access many links inmy email. Suggestions?

Tried uninstalling, selected to not include previous settings and reinstalled. Still having a problem.

Possible conflict with my firewall? How do I uninstall pop-up blocker?

Thank you

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.

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.

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.

When I click on a new tab, I get this black Google Search page, which I want to go to open my homepage. When I click on home, it does open my homepage. The image is attached. Any help on how to get rid of it would be appreciated. I do use New Tab Override, but it doesn't seem to be working.

Unable to login to my AAA account from my PC though I can with no issues on my android phone.

Please help.

Every time I start up firefox, it takes about a full minute to load. It shows an outline of the UI, but does not become usable for a while, windows also puts up a "firefox is not responding" window when the window is interacted with. After loading, opening a new window is unaffected, and page loading is snappy. just the initial launch is the issue. This remains true even after a clean uninstall + reinstall. Appdata folder was removed as well, and did not affect the issue. I do not have any antivirus software other than windows defender, so that should not be an issue. My hardware is also not likely to be at fault, as it is sufficiently up to date (upgraded within last year, not sharing specs here). Chrome starts up in less than a second for reference. Once again, a fresh install with a new profile has the same symptoms. Have tried every available guide to no effect.

I just did the most recent Windows 10 updates:

KB5037768, KB5038350, KB5001716

My version is 22H2 for x64 and .Net 6.0.30

Upon finishing the update and rebooting, Firefox gave me the PR_CONNECT_RESET_ERROR on all websites. Not other browser was having an issue. I've tried all the troubleshooting steps I can find. Is there an error fix based on what I am describing that I can now try?

Thanks!

Whenever I try going on to a multiplayer (e.g. .io) game website it will not let me access its server. The website itself works fine and I can access it but as soon as I press play or anything else it just says 'disconnected' or 'trying to reconnect to server'. please see if you can fix this as I couldn't find anything to resolve this problem do anything.

Using Firefox on windows 10 pro, 64 bit

Since updating to Firefox 125.0.3 (64 bit) , I am getting all sorts of website problems with font sizes. Some are all extremely small like on google news, others have widely mixed sizes, extremely large and extremely small. Even on this page, support.mozilla.org, I have to zoom 250% to make it readable.

I tried troubleshoot mode and there is no difference. The problems are still there.

I tried the Edge browser and the problem is not there.

I didn't have this problem before the update. I tried adjusting windows and the screen dpi, but I can't find a solution. Just seems to make things worse.

Anyone else having this problem? Any suggestions for a solution ?

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

Hi Firefox Support Community,

I've been exploring the reviews on SGEats and noticed some performance issues while browsing the site using Firefox. The site has numerous high-quality images and interactive elements which seem to cause slower load times and occasional lag.

Are there any specific Firefox settings or extensions that could help improve the performance for such media-heavy websites? Would enabling or adjusting hardware acceleration settings make a significant difference in this case? Are there known issues with Firefox handling similar content-rich websites, and if so, are there any recommended troubleshooting steps? I appreciate any insights or recommendations to enhance my browsing experience on SG Eats and similar sites.

Thanks!

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

Hi folks,

I've searched, but I haven't found anything to help with this particular situation ...

I love Firefox/Mozilla Sync and I use it a lot, but I've recently had a desire/need to set up a scenario that some may think perculiar - let me set the scene ...

• Work PC running Firefox - 1 profile
• Work VDI running Firefox - 1 profile
• Work laptop running Firefox - 2 profiles (work & personal)

Mainly for the sake of sending tabs to the appropriate Firefox profile on the laptop, I want/need to be able to config things in Sync to treat those 2 profiles as being different entities. Currently, it appears that all profiles on a device (or within the same user profile on a Windows computer) are treated as the same entity by Sync.

Any ideas on how to achieve what if trying to do? Is it possible with Firefox/Mozilla Sync?

Thanks for your time.

BTW., for clarity, if it matters, the devices listed above are all Windows. FWIW., I also use FF on Android and Linux ... and MacOS.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.
