Hi, I find that recently, my Firefox 102 (on MacOS 12.4, 2019 MBP 16) no longer displays colors correctly in pdf files. For example, in the attached screenshot I compare page 4 of https://arxiv.org/pdf/2201.08431.pdf seen in Firefox and Chrome. Could anyone give me some idea how to fix this issue?

I have my Firefox Firefox Privacy & Security History settings set to 'Always Use Private Browsing Mode.' Yet every time I open Firefox and visit the History tab, 'Recently Closed Tabs' shows a history of the websites I've visited. How do I disable this feature?

Hello,

My Firefox browser is crashing a lot after the recent updates. Not really sure what is causing the crashes but anytime I open any websites or try to do some work on the browser is resulting into unexpected crash. I have submitted several crash reports, but haven't had any solutions to the problem.

here the is one crash report: bp-921f5f10-a9ed-48d3-a1b4-f85680221122, bp-0abebf94-c5df-4a41-b9e3-9af8f0221122.

Can you please help us troubleshoot the issue and provide us with a solution if any?

Thanks Nishil

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

I want to re-order the add-ons / extensions in the toolbar shared with the search bar. Customize toolbar only has functions/icons related to the operation of Firefox. I want to customize the extensions toolbar, but how?

In the add-ons page, I can remove, disable, or enable extensions, but I cannot change the order of them.

As an example, there is an add-on for my Firefox account that is leftmost in the bar of extension icons. I would like to move it all the way to the right. Again, how would I do that?

Thanks for your help.

I have never had trouble with swiping left and right with 2 fingers to go back and forward between webpages. Recently, this has stopped working. I have updated Firefox to 111.0 and have double checked the browser.gesture settings as being "Browser:BackOrBackDuplicate" and the corollary for forward. This is for Firefox on a Mac Air running Ventura. Any advice is appreciated.

Hello,

Currently running MacOS Montery but the problem was still occurring on previous versions.

Whenever I use the green top left button to enter full-screen, the app immediately freezes and either crashes or has to be manually force quit. There are no reports in about:crashes and I there has been no success with troubleshooting mode or switching versions of the Firefox application.

Machine Info: MacBook Pro (16-inch, 2019) Processor: 2.6 GHz 6-Core Intel Core i7 Memory: 16 GB 2667 MHz DDR4 Graphics: Intel UHD Graphics 630 1536 MB

Any help towards a solution would be appreciated. Thanks!

i own a macbook and have recently switched from chrome to firefox- in my mac settings, it hasnt given firefox the permissions to use my microphone or camera. it doesnt show up the usual list to be able to allow the permissions. i've enabled microphone and camera permissions for the websites i want through firefox, but i cant even unmute myself. i think i need firefox to give me a popup and ask for microphone permissions, but it hasnt done that- and even if it did, i think it would show up in the list for allowing permissions through my mac settings (it shows applications that have requested for microphone access).

I have a user who runs SRS/Crystal Reports on their Windows 11 Lenovo laptop, but every time we go to the website where a Java-enabled pop-up window for viewing spreadsheets is supposed to load we keep getting a "A plugin is required to play this content" error message, but no option to install/approve the running of Javascript.

I have downloaded and installed the JRE and JDK on the endpoint device, but still no luck getting Firefox to load it. I am running the 32-bit version of the web browser, not 64-bit, so I am kind of stumped about how to proceed from here.

Is there a place I can manually download/install these Java plug-ins?

Thanks.

I have two computers, one for personal use and one for business. Somehow the tabs between the two computers are being shared and I cannot disable it. Both browsers are signed into different Firefox accounts, Sync is turned off on both, and there are no connected devices. Yet despite that, when I go to one computer, it pops up a Firefox icon (see attached) in the taskbar that lets me open the tab open on the other computer. This is incredibly frustrating and Firefox should not automatically share this information, and should not make it so difficult to disable.

Hi all. I've been using Firefox for years on my Mac. It's my browser of choice.

A couple of days ago, my Mac installed an OS update (v13.5.2). After the reboot, I opened Firefox and discovered that it, too, had installed an update (v117.0). But when I got into Gmail and tried to turn on desktop notifications, it said this:

Note: Notifications have been disabled in this browser.

And it's right--no other sites are sending me their usual notifications, either.

My problem is, I can't figure out why notifications are disabled in Firefox suddenly. I didn't disable them. I've tried clicking the lock on gmail's site and setting its permissions to allow notifications, but they aren't coming. I've checked my Mac's preferences, and Firefox has notifications enabled there, as usual. Gmail works fine on Chrome--notifications are working. I've tried reinstalling Firefox--no change. I've tried running Firefox in troubleshooting mode--no joy. Other sites aren't even asking for permission to send notifications. Like Gmail, they appear to believe notifications are disabled in the browser.

I've searched the web for solutions, but I can't find one that tells me where the enable/disable switch is. Can some kind soul please help me out here?

Thank you SO MUCH in advance!!

When I watch fullscreen videos in another browser (Chrome, Safari, etc.) on my Mac the video fills the entire screen. For some reason when doing the same in firefox the video does not reach to fill the entire screen and instead only occupies the middle. I tried screenshotting to illustrate this behavior but the screenshot was restricted to this middle zone as well. It seems like somehow firefox is shrinking the display size when no other browser exhibits the same behavior.

It also seems like if I want I can drag the video window around in fullscreen moving the whole video player around my display. I shouldn't have to drag the thing around to get the video to play right.

One particular website that I login to frequently in Firefox suddenly stopped opening the login screen when I click "Login." It opens in Safari and Tor browsers, but not Firefox. How do I get the login screen to appear? I have disabled enabled Pop Up Windows for this site, but it still won't load the login screen. It works in Troubleshoot mode. What does that mean and how do I get it to load the login screen in normal mode?

How do I turn off web translation permanently for ALL pages in Firefox 118.0.1?? It´s the most annoying feature so far from Firefox. Even if I delete all languages in preferences, it shows up on every page I visit.

How are my bookmarks stored when synced between devices? Are my bookmarks encrypted as well as my passwords/credit card info? This is from the Mozilla page regarding encryption:

"Your encryption key remains a secret, only known to you and your authorized devices." and "We store your encrypted data on our servers so we can’t read it."

I just wanted to make sure this also applies to bookmarks before I import all of mine.

Thanks for any help!

Firefox displayed a pop-up box on 10/30/22 or 10/31/22 that I accidentally agreed to. The appearance of all my tabs and screens changed. I'm not interested in any other themes. Community support said to install "System" theme to get the default back, but it's not completely the same. For example, checkboxes on forms display as white checkmarks which are hard to see. In my email, the messages and replies display oddly and are hard to read as the contrast is poor. HOW DO I GET ALL MY DEFAULT BACK?

Hi - I'm currently working abroad as a photographer, and am having great difficulty uploading image files larger than about 25mb. Is there a Firefox limit on files larger than this, or is there a setting I can use to allow larger uploads? Thanks, Alex

This blue icon recently appeared in the upper left corner, and it's there even when I watch video full screen. Clicking on it doesn't do anything. What is it and how do I get rid of it when I want to watch video?
