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 ?

Firefox automatically updated itself to version 126.0 (64-bit) and it was unable to display any web sites.

First I disabled Mozilla VPN but that did not fix my issue. Next, I disabled Microsoft Defender firewall software to no effect.

Finally I updated the shortcut to Firefox on my taskbar to launch the browser. This fixed my issue.

Hopefully, this will save other users from the same pain.

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.

확장프로그램을 설치했는데, 원래 대로라면 브라우저 상단 주소창 옆 도구 모음에 설치한 확장프로그램의 아이콘이 나타나야 하나 나타나지 않고 있습니다. '도구 모음 사용자 지정'으로 들어가서 직접 추가하려고 해도 추가할 수 있는 아이콘이 나타나지 않습니다. 이 외의 방법으로 사용할 수 있는 방법을 아무것도 찾을 수가 없는데 대체 어디서 어떻게 찾아서 어떻게 사용해야 합니까?

i installed a add-on program however this icon for using is not shown on browser's menu bar. there is not on personal setting, so i cannot find how do myself. wat should i do?

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!

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 had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

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.

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 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.

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.

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

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.

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
