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?

I have been using firefox for several years. Have my bookmark icon on the menu bar on the right hand top. The drop down list of bookmark appear on the right and submenus appear on the left of the drop down list. Recently one folder began showing the sublistings on the right side, it used to display them on the left. All of the rest are displayed on the left side.

The titles of these bookmarks displayed on the right are some of the shortest in length.

Is there a way to set this back to the left side?

I've mentioned this before but never have found good answers or feedback. Too often (well more than I'd like) I've closed Firefox and when I come back (start up Firefox again) my previous Tabs are lost. And, there is no option to restore previous session, nor closed tabs. Firefox keeps history, why can't it keep a history of previous tabs. And, why does it frequently not provide: Restore previous session. It seems that keeping a history previous tabs for a period of time isn't that difficult. Please enlighten me. This has happened to me (losing the previous tabs) more than care to remember.

This question was previously posted: "How to DISABLE the back and forward arrows that now come up on the left and right sides of the Firefox panel." There was only one answer but it didn't address the actual issue. It's too easy to inadvertently go back a page or two which usually screws up something I'm working on. Someone added these annoying arrows, there must be a way to remove or at least disable them. PLEASE HELP!!!!!

I'm using macos 12.5

Firefox will not open any windows.

When I try to open Firefox by clicking on the dock icon, nothing happens.

If I right-click the dock icon and select 'Show All Windows", a message takes over my screen. The message says "No Available Windows".

I manually deleted the caching directory in my homedir.

I then deleted Firefox, downloaded the latest version and installed it.

Attempting to open it fails again. The same symptom recurs.

I'm running the latest version - I downloaded it about 20 minutes ago. But I can't find the version number because the application won't actually open.

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

I change the default action for e.g. mime type PDF to a bash script. - works I get the filename of the downloaded pdf file in my bash script - works I can do things with this downloaded file - works

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.

What do I have to do to get the URL of the downloaded file in a bash script?

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
