How do I find out if a Firefox add-on is causing "rendering error" on a website I'm trying to log in to

I have been fighting with Xfinity.com for too long now over a "rendering error occurred: invalid time value" message when I log in to their billing function for my account. I am using a Windows 7 PC with whatever Firefox version is the most current.

Among the responses from their "experts," I see something that has to do with "browser add-ons may be causing your problem."

I have looked at my Firefox settings > manage your extensions as well as settings > manage your plug-ins. Under Extensions enabled I have 2: Norton Safe Search and Norton Safe Web. Under Plug-Ins enabled I have OpenH264 Video Codec and Widevine Content Decryption Module. That's all. Could any of these be causing the problem?

Does this "rendering" error have anything to do with Javascript? (I thought Firefox did not support Java so never paid any attention). If it does relate to Javascript, how do I fix my Firefox browser settings to enable it for the Xfinity.com website to see if that fixes anything?

This is so incredibly discouraging.

For the last few months (perhaps concurrent with a Firefox update, but I don't remember), Firefox seems to be having problems with Google-sourced stuff. It's intermittent, but the most frequent failures are searches using either the address field or the dedicated search field - much of the time I just get a blank page, and at first it looks like it might be trying to load something, but after awhile the "X" abort icon changes to the reload icon, signaling that it thinks it is loaded or has given up. Success or failure seems to come in waves or phases, not completely random - immediately retrying will usually not work. If I can get to the Google home page by typing "google.com" directly (which has a much better batting average than searching in the address/search fields, although not always), I can search directly on the Google page without trouble for some mysterious reason (perhaps that fills the page using AJAX rather than reloading - I'm not sure). But then clicking on one of the results might not work, because that initially goes to a Google URL before redirecting to the requested page. I've resorted to extracting the page location from that redirection URL just to bypass Google.

Other Google services have problems, too. YouTube's home page usually loads outlines of videos, but sometimes it fails to fill in thumbnails and other details or does so VERY slowly. Occasionally even reCaptcha will fail to load when I'm trying to log into some site that uses it. And even when something appears to fully load and function (e.g. a couple Google Sheets I use daily), often the "stop loading this page" X and hourglass on the tab will remain, indicating that it thinks something is still loading (in that case, it seems to never time out - I either click the X or ignore it). All these types of failures started at the same time, so they seem to have a common cause.

I have not noticed any problems with sources that are not owned by Google. And Chrome and Edge have no problems at all. So apparently it's specifically Firefox and Google that are not getting along. I'm running Firefox 108.0.1 (in PortableApps, although located on my hard drive) on Windows 11.

These failures happen even if I start Firefox in troubleshooting mode (which proves it's not caused by an add-on) or open Google in a private window so that there are no cookies involved. Since Chrome works, I also tried using the User-Agent Switcher add-on to pretend I'm Chrome, but that also has no effect. I expected to see tons of other complaints about this on the web, but there have been surprisingly few, and the only suggestion that seemed relevant (and effective for some people) was to set "security.tls.enable_0rtt_data" to false, but that has not made any noticeable difference in my case.

I waited through a couple Firefox updates, hoping it would just get well, but I've lost patience. Are there any new ideas out there?

After ColorWays was disabled I installed the FireFox Color add-on to recreate the theme I had been using

Everything works fine except when I open the Library window or Add-on windows I get the 'Dark Theme' instead of the 'Light Theme'

After experimenting with different colors I found that the 'Toolbar Color' setting here https://color.firefox.com determines whether the Library is light or dark

It seems only the very lightest colors allow the light theme even though on ColorWays the intermediate themes allowed it and had exactly the same level of brightness as the custom one I created

Is the there any way to independently alter the Library color without having to the change the Toolbar theme I read this https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/manifest.json/theme#colors but it doesn't mention the Library

Thanks

But can I get the download URL of this file in my script? It's not a dedicated URL in a tab - so I can not read the URL of the active tab.

It's a direct download link from, let' say, google search.

So basically Firefox updated itself yesterday. And since it did I have not been able to use the webcam (which I need to use on a daily basis in Google Meet). I tried using Chrome to see if it worked and it did, I just prefer using Firefox.

But then I started looking for information that might help and I found out about the New Profile feature which I did not know about. I made a New Profile and when I tried using the camera it actually did work there.

What am I doing wrong with the original profile? I have not changed any settings, is it possible it just changed on its own? And how can I restore it to how it was? I already tried re-installing Firefox a couple of times yesterday and nothing worked. I uninstalled it and installed it back again and the problem persisted. I deleted cache and cookies and still the problem persisted.

Please help! Thanks a lot

Firefox incorrectly formats 7 digit phone numbers for no reason by adding a "+1" and stripping out the "-"s (dashes). It is not up to Firefox to arbitrarily decide how I want phone numbers entered. This can be seen when you go to "Privacy & Security", "Forms and Autofill", and "Saved Addresses". Edit any of your saved addresses or add one if you don't have any addresses saved. Enter a phone number "456-789-1234", save the entry, and open that entry again. The phone number will now be "+14567891234". If Firefox wants to make the reformatting an option, I'm OK with that so that I can turn the intrusion off. version 109.0

To preface this I want it to be known that I have been using Firefox on this computer for a long time (around 2-3 years) with no issues whatsoever and today this has started out of nowhere.

As the title suggests I'm having connection issues with Firefox on Windows 10. To be more specific, out of the blue every-time I try to connect to a website it will say "Unable to connect, An error occurred during a connection" and such. But you see this problem ONLY occurs on Firefox and not Microsoft Edge. I have looked EVERYWHERE and everyone else that has met the same problem never found a solution and just gave up it seems. I tried all of the solutions listed on the Mozilla support page Here and NONE of them worked. It seemed my Firefox was dead. Other than the officially listed solutions I feel like I tried everything one could possibly do. Re-installing, Restarting, uninstalling all add-ons, deleting my previous profile, changing the proxy settings and many more. So all hope seemed lost and I was sure that I would have to abandon ship and just migrate to Chrome or Opera GX, neither of which sounded appealing at all. But then I came up with an Idea, my thought was since it was a connection issue maybe changing my connection would do SOMETHING, hell ANYTHING. And to my surprise using a VPN and trying again works. I am able to do all that I previously could its just going through a VPN. The thing is that it still doesn't work when it isn't connected to a VPN so what is the problem here, I don't really want to HAVE to use a VPN to use my browser so if anyone has ANY idea at all anything would be appreciated, thank you for your time reading this.

TLDR: Out of nowhere only Firefox couldn't connect to sites on windows 10 but everything else could, using VPN allowed me to connect to stuff but I don't really wanna have to be forced into using a VPN so any help appreciated, thanks.

After downloading about 10 GiB of source code and then building another 15 GiB, to install Firefox you need to use `./mach install` or more correctly: alias install='sudo sh -c "export MOZBUILD_STATE_PATH=$HOME/.mozbuild; ./mach install"'

But to re-install Nightly Firefox on the freshly installed (even the same) OS I will have to either save 25 GiB of source+build (+.mozbuild and other stuff) or to redo everything from scratch (needs at least 1h 20m). I'm having a hard time understanding all the abstractions and redirections from `./mach install` (and Makefile from ./obj-*/ which is automatically generated) to reconstruct a minimal set of things to install Firefox.

I need a bundle of files+dirs which is enough to install everything system-wide for Firefox to work properly. Maybe even simply run `./mach install` in this "minimal build installation" (if possible).

P.S. I'm using Debian based distro(s).

Hello. I know this is so random of a problem, but on this computer, when I try to play a video on YouTube, or playing a next video in a queue, the whole page seems to be not responsive and the CPU usage soars to 100% for a little bit.

I think there is a fix to this and you might check it out and message me if you want to ask for more information regarding this problem. Thank you for resolving this issue and it would really help in the overall performance of the browser. NOTE: This only happens when I only pick a next video or automatically plays the next video in a queue. Sometimes it happens but sometimes it does not.

A post having the same problem as I do.

Hi,

Recently I got a new gaming monitor (Asus XG27AQM, 240hz, 270hz overclock by factory). Evey time I boot up, open Firefox, and start Disney+ site, my monitor would shutdown after showing white noise screen for like quarter of a second.

Then after reading an article (link attached) with the same problem that I have, I tried to replicate the problem using Brave Browser, and there was no issue there. Then I uninstalled Firefox using an advanced uninstaller to remove all traces of files, keys, and others, then reinstalled a clean new Firefox, opened up Disney+ site and the same problem happened. The only solution that I don't know how to apply is how to reset Firefox completely, but I doubt it would solve it since I completely uninstalled & reinstalled it without leaving any traces back.

The following can be removed from being the cause of the problem, since I've double checked them and confirmed them in all ways possible: Monitor's Settings, 270hz overclock, DisplayPort, Windows 10 Pro settings, gaming related settings, power settings & updates , Graphics Card.

I've attached a link for a post that's describing the same issue that I'm having, just to save some time and maybe provide more description to my issue. I would highly recommend viewing it since it contains an answer to my issue which could be the right solution.

Thanks a lot in advance, I would highly appreciate any help. Have a great one.
