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'm using a new PC with Windows 11. I downloaded Firefox. When browsing in Firefox it has several times caused the whole screen to go black, and the only way to get back is to turn off and turn on again. Even then the Firefox page sometimes comes up again and I have to be quick to tap the X on top right to shut it down - or the whole screen goes black again! Then when I restart Firefox it re-loads the page, so I have to quickly exit before it happens again. So this morning when it happened I just did a full restart of the PC. Then I transferred all my tabs and other info to Edge, and will use that from now on.

What is new that is causing Firefox to do this?

I imagine I could also use Chrome, haven't tried that yet.

I wondered several times why firefox recovers old tabs when it chrashed. now i see that in my profile folder/sessionstore-backups the file recovery.jsonlz4 is some days old (while i was using firefox in the meantime very often) and does not update frequently as requested by about:config browser.sessionstore.interval = 15000 (15s). - this folder or the files are not locked. i can delete/rename them, they are not re-created - there is no file sessionstore.* in the main folder of firefox profile while running firefox - i am using 102.4.0esr (32-Bit) on a company PC (could there be any restrictions?) - the file previous.jsonlz4 seems to be created correctly when firefox is closed normal (which is not my usecase, i want to restore up to date tabs after crashes) - i am not using a private window

do you have any idea?

As you can see in the attached image of my old Overflow Menu, I had it customized with many buttons/extensions I often accessed throughout each day.

With the advent of FF ver 109, this functional flexibility has been completely lost. Now, there's no way to choose what buttons and to sort them in the Overflow Menu. In my view, an egregious loss of convenience and efficiency.

Please, bring back the full functionality of the previous Overflow Menu!!!

Hi folks,

Since the last 109.0 update I've noticed a strange behavior with Firefox.

Sometimes after watching a video stream in full screen, my toolbar changes and moves all my customized icons / extensions etc. into this "more tools" drop down menu. I can reproduce this by repeatedly switching from full screen to the normal view

This is so annoying and frustrating.

Does anyone know how I can fix this?

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.

Hello,

A few weeks ago something changed in my Firefox browser where popup boxes do not show. For example, if I want to download a file, the pop-up box with the options for downloading do not show. If I want to attach or upload a file, the popup does not show. Even if I want to change a setting in my my Firefox account, I cannot if it requires a popup box.

If I restart my computer (not the browser), the problem goes away, but eventually it happens again.

It is really disruptive. Now I have to do about 60% of my work in another browser. All of my account info, bookmarks, and passwords are saved with my Firefox account, so I would prefer to be able to use Firefox. Any suggestions on how to fix? I should also not--this has persisted despite updating.
