I'm not sure this is a problem with Firefox but I have run out of other options to look at. At first I thought it might be because the page uses a frameset (I know it's obsolete) so I created a version that uses an iframe instead. That way the html that needs to be acted on is not in a frame. It still doesn't work. I don't know why it works in stackoverflow's sandbox and jsfiddle but not on my website. Any help is appreciated.

Frameset version iFrame version

If you need to see the tabstrip code (it's virtually identical to the iFrame version): Tabstrip for frameset version

The script is supposed to hilite the selected tab with a red background. The rollover works fine (yellow background and brown text) but the selected tab color never shows up.

Original post: https://support.mozilla.org/en-US/questions/1315759

I wanted to bump this as I never received a satisfactory answer for the reason behavior was changed and it is still something that feels like a UX regression.

If I try to drag and drop a new bookmark onto the bookmark icon (the star with the line under it), it USED to open up Bookmarks and I could place the new bookmark where ever. That no longer works.

I CAN drag/drop into a folder on the menu bar but not into bookmarks directly.

With a Macbook Pro running Catalina (10.15.1) and Firefox 71.0b5 (or older versions) If FF is open on a second monitor connected via display port (I have 2 external monitors and built-it), when you Secondary click (AKA right Click) the context menu will often appear on the main Mac display rather than the monitor running FF. Also as the screen are different resolution the menu uses a smaller font. I have attached screen shots showing the two monitors. Assume this a FF bug?

Hello: FF dev build 73.0b7 w10p. (No stable on this mac - yes mac). I want to remove from the address bar, the 2 icons taking up space in the address bar, that I never use. Do I need to create a user file .css? I can if nec. The 2 icons are to the L of the addr. bar 1- "no trackers known..." & 2- "verified by amazon". The "remove" context menu item is grayed out. -What I really want is to SEE the address I'm typing into the address bar, when FF is NOT in full monitor pg mode. 23" W monitor & I often have FF in only 1/2 of the full monitor (so I can see another non-related window at same time). But only the down carot is visible in this "1/2 mode' status & I can't see anything of what I type, nor anything in the address bar already. I use the address bar search like 99% of the time & I really like this shortcut! (If it was fully useful, in 1/2 mode, even more). My guess is that removing those unused icons will allow more space in addr. bar to see what I'm typing -- right? Thank you.

For many years now I have used the beta channel. At the end of last week I checked for updates and received 73.0b11. I was already on 73.0 beta, probably b10.

Since that update I am unable to edit the contents of the address bar unless I launch a Private Window, where the problem doesn't occur.

I have tried using the "Restart with Add-ons Disabled..." option from the Help menu but the problem remains.

I am running on Windows 10, 64-bit, [Version 10.0.18363.592], with all the latest Microsoft updates.

I log into a secure site that grabs information from other secure sites which requires setting up passwords, authentication and ETC. Some these links need to be refreshed from time to time and requires an series of actions on my part to re-establish these automated links. The issue is when I try to re-establish the link, the first page will launch and then if I hit any key the link closes immediately. I think there is a security setting issue that is preventing me from making the appropriate re-linking procedures. Please note: This process work using Firefox at time however no longer works. I tried re-establish these links using Google and it worked.

Any advice would be greatly appreciated.

As stated in the title, everytime when I open a link in the operating system (i.e. clicking on a link in an email or opening a website with Alfred) while Firefox is not already running, the following happens:

1. Two Firefox windows are opened 2. One window opens the requested website (https://startpage.com in the Screenshots) but has no context items in the Menu Bar above. 3. The second opens at Home and has the items in the Menu Bar.

I am using Mac OS Catalina (multiple versions) and the issue persisted a complete reinstall (I wiped my hard drive and did a clean install) of the operating system. I tried mainstream Firefox 73.0 and Firefox Dev Edition latest beta 74.0b2. (Used `brew cask` to install) Also I do have another Mac on High Sierra that does not have this issue.

  • SolidWorks PDM appears to cause this, see information here: https://forum.solidworks.com/thread/220894
  • Until two days ago, running Firefox in Windows 7 compatibility mode solved the problem. However running Firefox in Windows 7 compatibility mode now results in blank tabs - similar to as described here: https://support.mozilla.org/en-US/questions/1231445.

So I am caught between a rock and a hard place. I have to switch off compatibility mode for browsing to work. But then Firefox crashes any time I want to download or upload a file.

If anyone has any idea's I'd appreciate it. I really don't want to be forced back onto Chrome...

So my Firefox Developer edition just got updated to the version 74.0b2 and I got this brand new address/search bar. One of the things that it used to have before it had been updated was a simple arrow-down button that, when clicked, showed the most visited sites. Now, after the update, this button is gone (pic related). This makes my experience with Firefox *extremely* worse, because now I don't have a quick access to open one of my most visited sites inside the current tab without starting typing their addresses. Is there any option to bring that feature back? Is removal of this button an already-made design choice for Firefox that will stay with us for the next versions?

In the latest version of Firefox Developer Edition, I notice the the urlbar behaviour has changed from what it was before and I want to change it back. Are there any settings in about:config that do this? In particular, I want to stop expanding and even showing suggestions whenever I click in the address bar. To me, this is odd and distracting behaviour and not what is done by other browsers so I want to turn it off.

Every UI update, there's something that makes me enjoy Firefox less and less and it becomes more and more difficult to make it something I feel is reasonable. Having the address bar suddenly take up more of the UI is bad design and not only irks me on a design level but it just doesn't need to be that large. I *know* it has focus because I did it deliberately.

So how do I turn this "feature" off?
