None of my installed Add-Ons will open. This occurred after running in "Refresh Mode" to correct a different problem.

The prior problem involved not opening bookmarks in a new tab even though the config:about entry was set correctly.

Is it possible there is a config:about entry that prevents any add-on from running?

Hello, I am wondering if there is any way to lock the toolbar so that it does not automatically pop up when you are in full screen mode and hover over the top area of the screen. I cannot easily play some browser games because they must be full screen and the toolbar popping up continuously interrupts the game.

To clarify, I do not want the toolbar to always be there; locking the toolbar so that it automatically shows when in full screen is not the solution I am looking for. I want the toolbar to disappear when I am in full screen and not popup when I hover over the top area of the screen.

Thank you for any help!

I have a keyword, "ht", for the OED's historical thesaurus. Here is the keyword's URL: https://www.oed.com/search/dictionary/?scope=HistoricalThesaurus&q=%s&tl=true

But it exhibits very strange behavior. When I enter "ht test" in the address bar, it goes to https://www.oed.com/search/dictionary/?scope=HistoricalThesaurus&q=test&tl=true and (for some unknown reason) returns a 403 error. If I refresh with F5 and resend, I get the same error. However, if I simply Alt-D into the address bar and press Enter, it goes to the very same URL and returns the webpage as desired, with no 403 error.

Does anyone know what's going on, or how to make the keyword work properly from the beginning? Thank you!

I'm trying to visit "Feedly.com," but as soon as I type "F" Firefox assumes I mean Facebook and pops up with a screen time blocker. There is no way to proceed, typing "Okay" and returning to type in the browser only restarts the prompt.

i've been in touch with you about an issue playing pogo games & need help please. The 1st firefox version I had worked great but changes have been made since then-I don't believe I was using enhanced protection control. The card games are not flipping correctly, some games are slow in moving pieces in a puzzle. Could someone advise me on what can be done? Thanks!

Lately, I'm experiencing less that optimal behavior and performance, so I'm building a fresh profile hoping to clean things up.

Like many of us, over the years I've collected and documented a number of tweaks. Before I re-implement them, I was hoping to publish them here to get opinions about their current validity/necessity, effectiveness, safety, detrimental affects, etc.

Would it be for me to post these about:config tweaks?

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

How on earth do I add Quant to the Firefox search engine? This info is no where under the help section, only lots of reading about warnings! In Firefox preferences I have made Quant my default browser so why is this so difficult? I vaguely saw a little warning message saying that Mozilla was not allowing this but this warning was hidden and I can't find it again. Firefox guided my to 'pin' Quant to the Firefox toolbar but every time I open a page to search I have to remember to hit the Quant pin. This is absolute nonsense. Please email me back and tell me how I can add Quant to my Firefox so that every time I open Firefox the Quant homepage will just be there. Thank you. Cynthia

I use Firefox on my Win11 and Win10 PCs. The Win11 version of Firefox has a button to restore the recent closed button, but the Win10 version doesn't. I wonder why?

When i try to open youtube.com for example i used to only type in you or even you y for firefox to finish the whole URL for me, but sometime last month it dissapeared and never figuered out why after ALOT of trouble shooting to the point where I felt the need to create a new firefox account. Can you fix this for me? or just make everything deafult?

Hello, when i click the 'extensions' icon in the toolbar, it redirects me to the extensions manager site, rather than opening a little popup with a list of extensions. How do i fix this so that the popup appears again?

I recall turning off this garbage at some point. Now it's hardwired without a way to turn it off in Search settings!!

Is there anything I can do to turn it off?

When I type in the search bar, I want to SEE my typing in the search bar. If I want to type in the address bar, I know where it is. I don't want a "unified" experience.

When I use the url calculator, the number will display as expected, e.g. if I type 900-756.07 Firefox displays 143.93 in the url. However, when I try to copy that number, the length of the numbers decimal places changes substantially, e.g. 143.93 turns in 143.92999999999995.

Is there a way to prevent it changing the result?

As we all know you can set certain wallpapers in Chrome. But can't find any such options in the Mozilla Firefox Browser for Windows. FYI, my version is 121.0 (64-bit)
