Firefox Support Forum

I have been with FF for years now but I started to notice a few months back that sometimes a web site I want to go to would not load with FF - a blank page would come up. Also, that some sites were very slow to load. I would go to EDGE and the sites pop right up with no problems.

Some examples - StartLogic, VERY slow to load on FF. United Health Care - I bring up the site, put my login info in and it brings up a blank page. I go to EDGE with both of these programs and no problems. There are other sites that I have the same problem with.

What's going on with FF? I would like to keep using it but I am finding more and more sites that act like this.

After I boot my system I am not able to open Firefox as it complains about an open instance. After around half a minute the file disappears on its own.

Deleting the lock file manually works for starting firefox, but seems to sometimes delete my cookies as well.

The issue is not reproducible by just logging out and in again.

Firefox Browser 113.0.2 (64-bit) "Mozilla Firefox for Garuda Linux"

OS: Garuda Linux x86_64 Kernel: 6.3.5-zen1-1-zen DE: Plasma 5.27.5 WM: KWin

The last update 113.0.1 was when I really noticed it being slow. None of the current suggestions have any effect. I have restarted several times, cleared cookies and history, flushed dns and have gone through all settings. Privacy is set at "standard" and not using a VPN and have turned off add blockers with no effect either. I have to check, but I don't think I have any add-ons except for color on home page.

If I do a speed test, ping is kinda slow, download is half what it should be at times, and every test shows ZERO upload all using several sites to test from . The only thing not done is shutting down av which I won't do. Anyone else seeing this issue? Any other suggestions than the go-to stuff here? Windows 10

Since the task limit option seems to have been obliterated? I believe the many more "programs" and the events they create for windows to handle is causing all sorts of virtual memory problems. Changing win10 advanced system settings from performance for programs to background services seems to have restored Firefox performance in my case, see: 10 advanced system settings win10 advanced system settings performance programs vs background services Is there an about:config option that would allow one to achieve the same "programs" limiting option as before? This laptop has 16 gig of memory and I used to successfully have even better Firefox performance with windows virtual memory turned off, but eventually I would get crashes. I can understand why Firefox was modified in a way to better localize the source of crashes, but in my case it has degraded performance. Thanks Mozilla for a great product I have valued for years!!!!

Just recently been experiencing the 400 Bad Request error on Kick.com (a live streaming platform) for about a couple hours now. Never had any issues prior.

Was informed that this same issue is happening on other browsers and the only solution is a "quick fix" (clear site cookies) which only works for literally a second. When the page is reloaded the error message pops back up.

Please help, thank you!

Since Ebay changed their format for auction ads the photos that are part of the ads open as faint negatives that can barely be seen. However, if you right click on one and save to a new tab they are fine.

I have a blog hosted on Render. The base URL provided by them is https://parker-codes.onrender.com. This URL works perfectly, in all browsers.

I purchased a domain from Google and then linked a CNAME record to the Render one: https://blog.parker-codes.dev. This URL works in many browsers except for Firefox Mobile (on Android). I receive the error "Address not found. The browser could not find the host server for the provided address."

- I flushed the DNS cache and checked that it propagated across the globe. I used nslookup to verify the domain resolution. - I tested in various other browsers on desktop (Safari, Chrome, Firefox) and mobile (Chrome) and they all work. - I turned off mobile extensions. I also tried in a private window. Still no luck. - I reached out to Google support. They don't see any domain or DNS issues on their end.

From all of this, it appears that the Firefox mobile browser has a bug that can't load the site for some reason. It can't properly resolve the host even though many other browsers can.

I saw an other article about the same possible but they had a problem with an extension but I dont have that extension but still have the same problem. Whenever i watch twitch or youtube and i alt tab or switch tabs my audio and video stops playing.

All typed text appears blue until you break it in some ways like pressing the spacebar or moving the keyboard cursor with the arrow keys. It happens at the firefox search bar as well, and search suggestions and autocomplete doesn't work whenever it happens.

I've been using firefox for last 15 years now to do my online banking with RBC. As of 2 weeks ago it has failed to open online banking on the RBC website. Google chrome however works. When speaking to RBC customer support they say it is a problem with firefox and will likely go away once firefox updates to a newer version.

Hope you can help with this issue since my browser of choice is firefox. Thanks

I was having issues playing videos. All I would get was a black screen, but I could hear the audio. Although some videos, like facebook shorts, played just fine. And I could view videos in other browsers. Tried several things I saw suggested on threads having the same issues, but ultimately I uninstalled firefox and then reinstalled it and it seemed to have fixed the issue. Hopefully this helps others having the same issue. I tried to suggest it on a few of those threads but they were locked.

I got this message today.... 'I then attempted to start Firefox, getting the error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem."'

I attempted to reinstall Firefox and am still getting this message. How do I fix this?

I am on Windows 10. I just updated my Firefox web browser and it send me an error message: "XUL Runner, Error, Platform Version 113.0.2 not compatible with min version equal or greater or lesser than 113.0.1. IS this a problem and what is the solution?? Bob Krause

I dont have the split screen where you see the email header on top and the message beneath. So when I click on an incoming email, it doesn't show me the message unless I double-click it.

Hello At the moment I is not able to log into an official Spanish WEB-site using Firefox version: 113.0.2 (64-bit) /Windows 11. I have sent the following question to the certificate issuer (accv.es):

I have a certificate issued by you which is verified OK. It works fine with:

https://sede.agenciatributaria.gob.es

https://www.suma.es

but with dgt: https://sede.dgt.gob.es/es/ I get this message when trying to log in to 'mi DGT': XML Parsing Error: no root element found Location: https://sede.dgt.gob.es/es/mi_dgt/index.shtml Line Number 1, Column 1: Can you help find the solution to the problem.? I can not find a DGT-contact to ask for help Best regards Morten Brinch

Accv.es have so far not given me any clues to what I can do.

Anyone having suggestions how to fix the problem ?

best regards Morten Brinch

Following a recent update (May 25th, 2023) I have lost all my notes. I know Mozilla does not monitor the Notes extension actively and the corresponding Github repo is archived (https://github.com/mozilla/notes).

Mozilla also notified the users about the decision to discontinue this service: https://support.mozilla.org/en-US/questions/1328311.

However, I found the "Notes add-on" useful, and kept using it. Finally with a sudden update in late May 2023, I have lost all my past notes. While searching for possible solutions for the data recovery, I came to find the following solution by " jscher2000".

1. https://support.mozilla.org/en-US/questions/1390845
2. https://support.mozilla.org/en-US/questions/1322197#answer-1384732

However, it was reported that though majority of the data was recovered by applying the technique above, lost notes were not among them: https://support.mozilla.org/en-US/questions/1390845#question-reply

For anyone with similar issue I am describing below what worked for me. Following the suggestion by "jscher2000" I first generated the "Old Firefox Data" folder on my desktop. This is how I did that: From the Firefox browser window, click on Help -> More Troubleshooting Information -> Refresh Firefox and follow the instructions.

After creating the "Old Firefox Data" folder you will be able to see one, or multiple, "profile folders" therein. On my system I was able to see multiple "profile folders".

Next, type "about:profiles" in the URL space of a Firefox browser. I saw only a single profile (the default profile) on my screen that followed. Next, you need to "create a new profile" and point the system to one of the "profile folders" inside "Old Firefox Data" folder. Lastly, hit the "Launch profile in a new browser". If you can not see your old notes, try with another profile folder inside "Old Firefox Data" folder.

This is what worked for me (Mac OS). If there is any better solution please suggest that.
