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.

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 All,

I'm trying to modify various userChrome.css attributes of Tabs in Firefox 109.

However, code that worked in FF 88 is seemingly no longer working.

Is the below code outdated?

I would also like to change the appearance of #TabsToolbar from translucent to either a solid color or a background image. Is that possible? Right now, you can see icons from the desktop through the Tab bar, and there appears to be a strange curved, black overlay colorizing it. See attached screenshot.

Thanks for any input!

/* MISCELLANEOUS TAB ATTRIBUTES */

  1. TabsToolbar { /* tab bar */
 -moz-box-ordinal-group: 3 !important;
 padding-top: 0 !important;
 padding-bottom: 0 !important;
 height: 25px !important;
 background-image: url("bkmr_back.gif");
 border-top: 1px solid #afc0d2 !important;
 border-bottom: 1px solid #8698aa !important;

}

/* Change the color of selected tab */

   .tab-background[selected="true"] {
       background-attachment: none!important;
       background-image: none!important;

background-color: #eef5fc !important; /* background color only, not border */ }

/* Change text attributes of selected tab #8698aa to match bottom tabstoolbar line color */

  1. TabsToolbar .tabbrowser-tab[selected] {

font-weight: 800 !important; color: #000 !important;

       border-top: 1px solid #8698aa !important;
       border-left: 1px solid #8698aa !important;
       border-right: 1px solid #8698aa !important;

}

  1. TabsToolbar .tabbrowser-tab:not([selected]) {

font-weight: 600 !important; color: #000 !important; /* non-selected tab text color */

       border-top: 1px solid #afc0d2 !important;
       border-left: 1px solid #afc0d2 !important;
       border-right: 1px solid #afc0d2 !important;

}

/* Change the color of non-selected tab */

  .tab-background:not([selected]) {

So this crazy new update has broken my Firefox in these ways:

1. All my bookmarks on my bookmarks bar have been deleted. 2. I can't drag any new links to the bookmarks bar 3. Overflow menu for apps is empty and will only let me drag Firefox defaults to it such as settings. Dragging apps to it is impossible. It "is" possible to pin items by using the Chrome puzzle piece..

Firefox: 109.0 OS: Windows 10 Pro

Using troubleshooting mode has no effect.

Hi there. I use Firefox in macOS, and I always have multiple windows in different Desktops.

As you know, Desktops in mac are numbered, and each App in the Dock has the option "Assign to" a particular Desktop number or Desktops in Display X. But that is too limiting, because all windows appear in the same Desktop. I'd like an option or Extension in Firefox that allows me to set each Firefox window to a particular Desktop number, so that I don't have to re-organize all my windows every time I restart Firefox.

Does anyone know if there is anything like that?

Hi! I am hiding the toolbar when browsing web pages to maximize the screen spaces. However, when playing full-screen videos (all HTML5 videos), the lowest part of the video are missing. It seems like that part are squeezed out of the screen. If I uncheck the "hide toolbar" function, it fixed. See the lowest part of the attached image.

I'm using the ff dev edition, 110.0b6, but the bug also happens on my ff 109.0 OS: MacOS 13.2

I am often switching office and change my system default printer always first when I am in a new place. I learned from the community here that the right thing to do for having Firefox/Thunderbird follow this choice is set print_printer to 'default'. The problem is that this does only work for a while. As soon as I use the selection dropdown in the printing dialog (e.g. to exceptionally select the PDF printer) it will overwrite 'default' by that printer. The consequence is that from that time on I have to manually select the printer or got to the config editor again to set 'default'. Is there any simple solution I overlooked?

If not can you tell me how I can make a feature request? A simple solution would be to include something like 'System Default' in the dropdown list in the printing dialog. Although for my taste, it would be better to have the selection in the printer dialog only temporary and return to the previous printer selection for the next printing.

I recently updated to v109. So far, so good. But...

this is on a laptop (being replaced in the next few days) with a rogue keyboard -- some keys barely work, others occasionally go wild. And after a recent session (several days and two reboots after installing 109) in which the keyboard did the latter in the Address Bar, the Status Bar at the bottom has disappeared. And I can't get it back; there's no apparent menu item or setting.

I'd really rather just port this profile to the new machine, but can't if there's no way to reverse this...

Menu item that's buried? Setting? About:config entry?

I'm running MacOS Ventura 13.2 on a M2 Macbook and Firefox 109.0

I can not select a Downloads folder and even if "Always Ask" is set, all Downloads of all types fail immediately.

See quick screenshare here: https://www.loom.com/share/c5bc3563630f4d1182199ee7787e32f4

I've tried many of the common things: uninstalled/reinstalled start with add-ons disabled refreshed

None of them solved the issue.

Any thoughts/insights?

Thanks!

this is the question dougumbarger asked in 2022. There does not appear to be a solution posted I now have the same problem. Especially noted with ticketing sites like Ticket master, Eventbrite.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. How do I get the autofill to start working again

Hi All. Love FF but there's one thing that's driving me crazy... the different color of the Library window (see screen grab). The main window is this nice dark "cool gray" color, but the library window is this greenish color.

Is there a way to change that? I've had the userChrome.css file installed and feel fairly comfortable making code edits.

Thanks in advance.

Hello,

I downloaded Firefox on a new computer. I logged in with my existing account and synced my data

This was successful. All of my bookmarks and extensions were downloaded properly.

I went into the customize menu to alter my toolbar. However, there were no icons for any of the extensions that I added, such as Bitwarden or Ublock Origin.

Due to this, I am not able to add these extension icons to my toolbar.

I verified that the extensions were all properly downloaded and that they work as they should.

I have already attempted to restart Firefox, uninstall and reinstall certain extensions, and to reinstall Firefox entirely. However, my extension icons do not show up still in the Customize menu

I am not trying to do anything in the Private Browser.

How can this issue be resolved?
