When I open a PDF in Firefox, a box covers the right half the page demonstrating the highlighter tool. It never leaves. It blocks half the page and prevents me from reading and/or printing. Please help. It's making my work impossible.

I have a different theme and cursor on my system. I would like to include them in Zen Browser. They are Candy Mac and Azenis respectively. There is no setting to do this. Many other browsers have System themes as an option.

On Debian 12 running XFCE the shutter function in the top right orner is missing. This is a option like close, minimize, maximize that allows Linux GUI to only see the title bar, so it is out of the way of other screen applications. It is represented by the caret.

I'm expressing a strong dislike for the very shortened list of paper sizes in Firefox in the Print function.

One big reason I use Firefox over Chrome and MS Edge is the long list of paper sizes. Now the list is a small fraction of what was there. And how many people know what sizes are the likes of A4, B3, JIS-B4. It takes extra time to figure out what works best.

The old list with Letter Plus, Letter Extra, Legal Plus, etc. was MUCH MORE useful. If I were to eliminate anything, it would be the meaningless A5, B5, etc.

At least give us an option of the old or too short new list of paper sizes.

If my comments aren't appropriate in this forum, please provide a link to where I can submit it.

For some time now, firefox literally has NO horizontal scrollbar, even on sites when it is clearly needed.

How do I make it visible? Is it a Windows 10 & 11 thing?

Also, before anyone suggests it, several posts online mention to go to Settings > General > Browsing > Always show scrollbars. These posts are over a year old, however, and this option DOES NOT exist.

Thanks in advance.

Since FF35, using linux with e26wm, the title bar is gone. Screen seems to be stuck in full setting - F11 just shows/hides top right min/max/exit toggles. Min/max doesn't work. Going to customize toolbars, title bar option is there and checked but the option itself looks like it is grayed out (lighter color). Screen cannot be resized. I am used to a menu accessed via rt. click on the title bar but that is gone (I do have access to that menu with combo alt/rt-clk anywhere on screen - see below). That menu had a shade option (window shade like) which I used extensively but thats gone. If I click alt-rt click anywhere on the screen, I can get my missing control menu back without the shade option but with a borderless option checked which cannot be changed. I am fully aware that linux + E26 is kinda out there but have been all over my settings (includes border settings which firefox ignores). I can't find any permission settings on config/js/pref files which may be a cause. Thing is, mozilla thunderbird's screens work and title bar is in place with desired menu, etc. as do all other apps except ms edge, which leads me to feel it is a firefox setting somewhere and I believe it is the side thingy that everyone seems to love in chromium/chrome might be the cause - the tabs on top option which I don't have an interest in. Sorry for the length here but I'm at my wits end and all a google search offers (here as well) is to go customize etc. etc. Any thoughts would be greatly appreciated - been using FF on linux since day 1 without any problems I couldn't figure out till now.

My computer was slowing down so I opened task manager.

I discovered that Firefox had 40 different things running and was using over a gigabyte of memory. I could not identify what the various things Firefox was running. Or what tab they related to.

It would be useful if Firefox could indicate in tax manager, what is going on and permit me to end task individually rather than shutting down the entire browser.

Meantime, what can I do to keep this from going on?

I have already shut down Firefox several times as well as restarted my computer to no avail.

Also cleared the cache and cookies

As of today (?), on certain websites, such as Reddit, or on certain elements of some websites, such as text on Google Search's accordion components, Japanese text is suddenly being rendered in Chinese (see images). I have seen reports about this by other users (on Reddit).

This is fixed if `ja` under `font.cjk_pref_fallback_order` is moved to the front. However, I found a comment on Bugzilla stating that the `font.cjk_pref_fallback_order` setting is only honored if Firefox can't determine system font preferences, but `about:support` lists my locales as ["en-AU","ja-JP"].

Probably a bug?

Hi,

I'm working on a Firefox extension where I need to detect print event. I've tried the following approaches:

• beforeprint – Fires immediately when the print dialog opens (works correctly in Chrome).
• afterprint – Fires immediately when the dialog closes (works correctly in Chrome).
• window.focus and visibilitychange – Work inconsistently with noticeable delay, depending on how Firefox handles focus/visibility updates after closing the dialog.

Questions: 1. Is there a reliable way in Firefox to detect print event? 2. Are there any known workarounds or events that could be used for this purpose?

Thanks.

I am locked out of my desktop Firefox because it doesn't recognize my Primary Password that I use on my laptop and my iPhone. The laptop and iPhone Firefox opens but not my desktop which shows I am signed in but it also states I changed my password which would explain why my primary password doesn't work. What to do?

Hi!

I was shocked when I recently visited a website of a company that offers IDEs. I've downloaded one of the IDEs a couple of weeks ago and now that I've came back to the website looking for plugins, the website still "knew" which version of the IDE I had downloaded because it gave me warnings about plugins not compatible with my IDE version. Now: My privacy settings in Firefox are "strict", the option "Delete cookies and site data when Firefox is closed" is checked and I've closed Firefox several times in the meantime. Still, the website has information about my identity.

I would have expected that with these settings something like what I've described wouldn't happen. I must say, I'm quite disappointed. Is there anything else that I can do within Firefox to enhance my privacy?

Plugins that I've installed: CanvasBlocker Cookie Autodelete Decentraleyes Forget Me Not NoScript

I deleted my browser and reinstalled to try and help with some lag issues. Now every time I turn the computer on, this message displays-before I have clicked a link to open FF. What is this trying to tell me exactly?

I have a number in a circle showing up on the Firefox icon on my taskbar. For a while it was a number 1, then that went away. Now I have a number 5 in a circle on the icon.

How do I fix firefox browsing on a laptop when I can login to an account but NOT be able SEE a page after it loads? It has always worked until I think outlook interrupted my browser with a mail notice while firefox was negotiating my request.

I tried it on another computer using fiefox and it works as expected.

I have cleared my history and that one request still fails to display the page to enter needed info to continue. It seems that one process interrupted by outlook somehow corrupted something for that one request.

Weather I initiate the login from the firefox most s login's OR type the web site in the command line in firefox makes NO difference!

I need to fix this on one computer. I would also like to STOP outlook from randomly interrupting me with mail notices as they come in.
