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.

I love Firefox!!! But ..

After I updated I an no longer see the bottom 20% of the text in my All Bookmarks->Bookmarks toolbar where my toolbar only displays the text of the drop down name.

It seems to be a recurring issue where new versions really mess up the spacing in the drop down menus of the toolbar mostly (not this time).

My menus are just Perfect now .. although I'd love for the menus shown in the 'manage bookmarks' window to have Exactly the same spacing as the Firefox toolbar menus (the 'manage bookmarks' window has Much larger spacing and is a bit of a pain to use due to this).

Here's my no doubt primitive userChrome.css

menupopup:not(.in-menulist) > menuitem, 
menupopup:not(.in-menulist) > menu {
  padding-block: 3px !important; /* reduce to 3px, 2px, 1px or 0px as needed */ 
  min-height: unset !important; /* v92.0 - for padding below 4px */
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

#placesList treechildren::-moz-tree-cell-text {
  font-size: 11px !important; 
}
#placesList treechildren::-moz-tree-row {
  max-height: 10px !important; 
  padding-bottom: 0px !important;
  margin-bottom: -3px !important
}

I recently updated my system (OpenSuse15.4) which included a Firefox update to version 109.0.

I regularly use my mic for google voice, however even though I can select my microphone in Google voice, It never shows any input.

I tested my mic in other apps and it works fine. When I pull up my systems pulse audio volume control (pavucontrol), it does not show firefox in the recording tab like it used to when using Google Voice.

To test to see if it was a Google Voice error, I also tried testing my mic at https://mictests.com/, and zoom.com, but after selecting my desired input device, mictests.com was also unable to record anything, and again, pavucontrol did not show anything being recorded.

I have attached an image of pavucontrol that shows audacity recording audio. Normally, I would also see Firefox in this window when using the mic.

For some reason my automatic email signatures in Outlook Live websites (outlook.live.com and owa's) become gibberish (see attached image). I have been having this problem for a while now (aka, not only after the last Firefox update), but it is intermittent.

I have already tried identifying whether the issue is in an extension or in Firefox itself, but without success. Whenever I restart Firefox in Troubleshoot mode, it solves the problem. But disabling all extensions and restarting Firefox does not. Restarting Firefox (not in Troubleshoot mode) sometimes solves the issue, as well as right after an update of the app; but not always. Starting Firefox after a computer restart usually brings the problem back. This problem also happens in my laptop (MacBookPro), so it is not restricted to this computer (macMini).

I would appreciate some help in identifying the culprit, so that I may contact the appropriate support team (if not Mozilla itself).

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?

I have searched the "Knowledge Base" to no avail--no solutions, just others with the same problem. Every day a handful of fresh Trouble Reports pop up on my desktop, even though Firefox is not even running (as verified through the Windows Task Manager). It got so bad, I uninstalled/reinstalled and the problem persists. Otherwise, the browser works fine. My expertise lies outside trying to decipher arcane strings of data buried deep in the bowels of my computer, and frankly I should not have to start hiking up a steep learning curve just to get this to stop. I should add, I have been a fiercely loyal Firefox user since its inception.

I'm not super happy about sharing internal data with the rest of the universe, but have done so anyway in hopes we can get the madness to stop!

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

Hi there,

I have a laptop running Windows 10, plus the latest version of Firefox. The laptop has a built-in webcam. I have also connected an external webcam via USB. This second camera is better quality and preferred, I visit a web site. When I first activate the camera, I am presented with a dropdown of available cameras. The USB camera appears in the list. All is fine. I instruct Firefox to "allow" this camera to be used. (first image) However, after a short time, less than a second, the same dialog is shown again, this time without the USB camera. (second image) There have been no actual hardware changes. I can then click "allow" again and the *integrated* camera works, i.e. not the desired camera. So, two questions, really. First, what just happened? Did Firefox try to control the USB camera, find that it couldn't, and redisplay the dialog showing only the "controllable" option? Second, my desired endpoint here is for the web site to use the USB camera. How do I achieve this? I can easily do this with Chrome but I like Firefox. TIA.
