Diễn đàn hỗ trợ Firefox

Hello! I have used Firefox on and off so I don't have a time frame of when this would have started exactly, but I have had some random completely black screens on both of my monitors dating back to at least 2-3 weeks ago that can only be fixed by powering down the entire PC. I've reinstalled my (NVIDIA) GPU drivers, rearranged display-port cables and just about anything before finally finding a fix, switching to edge. So far I've gone a week without black screening when with Firefox I'd get around 4 give or take a week (some days getting to 3 alone). I don't know what could cause it but I have noticed it only happens when first starting a video. Mostly YouTube but other video sites seem to have also caused it occasionally, I would just like to know what could be causing this, as I do prefer Firefox vastly and would like to switch back as soon as I can.

Will provide anything else as necessary!

For some reason the main texty font is OK in chrome but not in FF

Any ideas?

thanks

Recently, when I try to play a video on YouTube on Firefox, there is a flickering brightness effect (some aspects of the video seem to flicker bright and dark quickly) which is distracting and makes it difficult to watch anything. The effect persists even when launching in troubleshooting mode, and disabling hardware acceleration and restarting appears to have no effect. I have also been unsuccessful refreshing Firefox. Nevertheless, this issue is absent on Safari and Chrome when watching the same video.

Watching a solid colored video like this helps see the issue best, if it is happening to your device: https://www.youtube.com/watch?v=hJmFYZEcpZA The brightness switch is visible even when pausing the video.

When I find the same video two different places (ex: the Apple Sept 12 Event on Apple's site, versus on YouTube) only the YouTube video has the issue. However, I can't find any settings to change on YouTube to help this.

I have a problem with PDF showing.

If I take PDF generated by the lilypond and I open it from link like https://gitlab.com/lilypond/lilypond/uploads/f51162c65d5194db6dd3b4fb86fa4e42/bug.pdf, PDF looks well. If I open same PDF from disk by using link like file:///tmp/bug.pdf , PDF looks different (wrong). Some ledger lines missing.

I am running firefox 117.0 (64 bit) for Arch linux.

Ever since doing a refresh of FF two days ago, Yahoo mail doesn't work. I'm able to log in but contacts are missing and I cannot refresh the page without getting "The page isn’t redirecting properly." To log back in I have to either shut down FF (my settings are to clear cookies on shutdown) or clear cache or history every 5 minutes. I have not changed my extensions or other FF settings I had before the refresh. I have cleared cookies, cleared cache, added yahoo to the cookie exceptions list and nothing helps.

Thank you.

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!!

This is the same problem listed below. Recently upgraded to Ubuntu 22.04.3 LTS and Firefox 117.0 a few weeks ago and can't get the files to attach. In fact it won't open the file system. Tried removing all extensions as suggested and rebooting, but nothing changed.

This issue was introduced by 117.0 Now I must click all URLs twice to get the website visited.

O.S.: MacOS 11.7.9 (BigSur), Firefox 117.0

JOOP!

I just added "TextArea" to my extensions & it only can be selected by clicking on the picture puzzle icon at the right edge of the address/search bar for a dropdown box of extensions. I would like to display it and a number of others now only on the dropdown on visible toolbars, but can't move them there. When I select "Customize," it shows some basic icons not being displayed, but only the basics and does not include extensions I've added recently. I used to keep icons in the All-in-One Sidebar on my left margin, the Vertical Toolbar on my right margin & the bottom Status bar in pre-version 57 FF and don't want the extra hassle of having to use the dropdown for commonly used extensions. How do I get these icons moved into an existing visual space on my browser? I have 3 36" HDMI screens & plenty of real estate to play with, but no way to use it in FF for new extensions. Do I have to continue to use alternatives like WaterFox Classic & Pale Moon?

Hello ! ..I need help ! I accidentally refreshed Firefox, and now I cannot re-open all the tabs and the 2 windows I had prior to the refresh -- is there a way to get them back ?! I really woudl hate to have lost them all... Cheers

All images, webm, gif etc. are loading, seemingly, exactly 20% upscaled compared to the real resolution of the media. I'm using a 4k TV (S95B), but I have desktop scaling at 100%, and browser scaling at 100%. I don't believe it's a GPU or OS system wide type setting because windows photo viewer gets pictures right. I'm using ShareX to measure the pixels of pictures. I can even load a local picture in a tab, and it will be upscaled beyond its native resolution. I have no idea why. I've tried a bunch of things, like setting layout.css.devPixelsPerPx to 1.0, which did nothing. I've reset Firefox to no avail, and I have noticed that Chrome is doing the same thing, which would usually indicate it could be the OS or GPU driver, but again, other apps load images perfectly normally. Do apps have categories on Windows now, where something like a "browser" can be told to treat media files differently than other media handling categories? I'm really lost at this point, nothing seems to work.

This problem started yesterday and I cant seem to fix it where youtube is too wide for my screen without any indicator on the top of my screen saying that its zoomed in and I cant watch any videos fullscreen. This glitch isn't a problem on any other websites. I tried opening and closing the browser, I tried restarting my computer tried clearing my cache and cookies and I tried using different accounts but none of them seem to fix the problem!

Photo 1: What it looks like right now Photo 2: What it should look like (had to use private tab) Photo 3: What search looks like Photo 4: What search should look like Photo 5: I cant see any videos fullscreen

UPDATE - - problem solved - - Using Firefox Troubleshooting Mode I found that the problem was ''''caused by an added extension '''' which has been turned off (I hope) One thing I don't understand though is that I fixed this in Firefox but it also fixed it in Chrome. All images show up in both, so how does one browser fix a second browser? I have yet to check Safari but I never use that one anyway, so I'm not going to push my luck! Thanks Terry.

- - - I have a LOT (hundreds) of images that do not show up on many pages and each one is labeled,

403 Forbidden in the Network Monitor.

There are images that do show up on the same pages and the amount varies.

Those are labeled with a green 200.

What causes this and how can I fix it so they all show on the pages?

and do I have to fix each and every one? That would take months.

Thanks

When I click on a link from an email or document, Firefox opens but goes to my homepage and doesn't go to the link page. I've tried setting my home page to blank, changed the settings for opening a new tab or window, and the one for "switch to it immediately" but it doesn't seem to help. How do I fix this? Thanks, A PS I'm on Mac OS 10.15.7 Catalina with Firefox 117.0

Have had this problem for a couple of years now, across dozens of Firefox updates. Decided to finally make a post since have not been able to find anything online.

Normally not too much of an issue as I can edit on a different computer through Firefox Sync (or through the Bookmarks manager), just posting to see if anyone else has seen this before.

If I open a Bookmarks Toolbar folder, then right-click a bookmark to edit it, the contextual menu appears behind the open folder dropdown menu.

Issue persists even if I reset Firefox, or even completely uninstall / remove ALL its bits and pieces, reboot, and do a clean install.

Since I am on a Mac, I use the AppCleaner app from FreeMacSoft to completely remove an app.

This happens only on one of my two Macs. Have never seen this behavior on any other Mac (I work on dozens for work). Both my Macs also have Win 10 installs through BootCamp and those two also behave normally. I use Firefox Sync across 4 Firefox installs (2 Mac OS and 2 Win 10), an iPhone, and an iPad.

Screenshot enclosed below. Feel free to ask for any other info you may need. I recognize this may not be a Firefox issue. There seems to be a funky interaction between my install of Mac OS and Firefox. This occurs only with Firefox. All other apps exhibit normal menu behaviors.

Tech details: Firefox 117.0 Mac OS Catalina 10.15.7 running on mid 2012 15" MacBook Pro with 1 TB SSD and 16 GB RAM

Many Thanks!
