Firefox supportforum

I keep getting the message 'Access to clipboard denied - please update your browser Preferences'. (Firefox in Windows and Mac).

But Firefox Preferences shows NOTHING about the clipboard.

This seems to be the default in the latest Firefox – before I updated it there was an annoying popup that asked me to select Block/Allow access to clipboard *and I always clicked Allow*. Now it is blocked and I cannot turn off the block.

This has made Firefox unusable.

Greetings!

I use a Mac 27" desktop and when trying to log into Facebook receive this error message:

Login approval needed We noticed a login from a browser, device or location you don't usually use. We need to confirm it was you before you can get back on Facebook. Learn more

I am not understanding the browser & desktop issue. I was able to log in to Facebook on my iPad, but still unable to access the desktop. I seem to be in an endless loop with Facebook.

Since a couple days ago, my Firefox (latest version as of now, 95.0.2) stopped downloading any files. The "Download" / "Save as" dialog never appears. Whenever I click any direct link on any website, something flashes on the current page (probably the input focus moving or resetting), but otherwise nothing happens. I have then discovered the files with random names and .part extension are created in the Temp folder, and they eventually do download - the files are complete, archives pass integrity tests etc. But there is no download progress indication, no entries in "Downloads" etc.

This is on Windows 10 x64. I have not done anything since the last time it worked (which was about 4 days ago). Maybe FF was updated, not sure, but I'm absolutely certain I have not installed any new plugins or changed any FF settings. Maybe there was a silent plugin update?..

Note: 1. My download folder is not the default, it's D:/Downloads. I have verified there are no problems with this folder, and I have re-selected it in the FF settings. No change. 2. "Restart with add-ons disabled" - downloading works! 3. I then did a normal restart and disabled every single add-on. Then restarted again. Downloading does not work! I have then double-checked that I disabled every addon visible in the settings - add-ons.

So it is something that works in the "no addons" mode, but disabling addons in the normal mode does not fix it. What could it be??

Thanks for any advice! I thought I've seen many odd bugs in different software (have many written many myself, too), but this is a new low.

Portalbella web site use to say use IE9 (which no longer exists). So why can I sign in with Edge but Firefox says invalid ID or Password? I may have to start all over again or just use Edge.

I've recently noticed that some icons on websites are showing up as "asian" characters. I haven't knowingly changed any settings, gone to any strange sites, nor added any extensions. I've tried clearing the cache and even removed and reinstalled firefox and the few extensions I use, which are the common ones like adaware,etc. Nothing has seemed to work. The icons range from ones that link to facebook, twitter, etc to the search icon. If I inspect the icon it says the font is "MingLiU_HKSCS" I've checked the setting and it says the font is times new roman and even unchecked the box that says "Allow pages to choose their own fonts, instead of your selections above" but neither seems to work. Thanks for your help

Hope someone can help.

When I use full screen for some websites, it darkens after about 2 - 5 seconds and my cursor also becomes harder to move. This only started to happen recently.

It is not my computer settings, I've tested this in Safari and it works normally. This makes videos unwatchable. It is like a dark screen suddenly appears over the video and only comes off if i move the cursor. It happens with netflix and prime but not youtube, udemy.

So, I just noticed today that my bookmarks section is having the same issue again that it had a few updates back.

I tried looking into repeating what I did last time, but it doesn't seem that this is the issue this time as the settings have not changed from when I went into to edit them the last time. Meaning this might be a whole new issue. I *did* however notice that there is a new and odd section listing in about:config under the following:

browser.bookmarks.defaultLocation SxQPPk-c1zth

Does anyone know if this is the issue, and if so, where this is supposed to really go?

Thanks in advance for any help you can offer.

when i close a tab the app stays open in the task manager. The TM shows 14 open apps and I only have three tabs in my browser. That eats up memory for no reason.

I just installed firefox on a brand new Windows 11 PC and Firefox continually crashes. I did a clean install and still I can't go a couple of minutes without a tab crashing.

Here are a bunch of the most recent: 44ff3780-ddbd-4fa7-88a3-a606a364988b 3b24eea5-9a72-46dd-a635-273a20269eb3 056a49bf-0388-4b16-ab5e-9e023ebfb3d8 08b199d3-9631-4cfe-9b3b-44a8869c3949 02cf78b7-9c94-4905-9c0e-49e38998453f 66220c6a-3466-4fed-b394-f8d00a0cdee5 26c2bfba-1f66-4257-b4a5-76ac54a7dc65 532a5cda-40b2-4dff-aae9-2bb387e5d64f 32670407-0436-47f1-9728-ac9730a3b320

(SECOND occurrence of this problem; not sure HOW previous instance resolved - my short-term memory ISN'T the best at present!)

Have taken all recommended steps short of completely refreshing (renamed a file titled 'config.json.old' as it was the ONLY one with a 'json' filepath suffix) because I don't want to have to relocate (another) existing session / configured profile by trial & error if avoidable - 'cookies' were removed along with history / cache cleared; reset / deleted related browser registry entries as directed, activated ' Troubleshooting / Safe Mode' contingency and STILL can't download anything (additionally, tried to do so with and without limited-time Malwarebytes web protections).....want to CONTINUE using Version 95 because by ALL indications and from what I'm seeing in Comments, my instincts about newer ones - were sound, WELL-informed.....please advise ASAP? Thanks!

I went to Privacy and Security permissions and in the box "Settings Camera Permissions" it appears to me that I'm only allowed to remove permissions, not add them. The box says that it contains the list of websites that have asked permission to use my camera. The box is empty.

I tried putting the desired website in the line on top, thinking I might add it, then tried alternatively both "enter" and "save", and nothing was added to the box below. The box remained empty.

As stated in subject line. FF 95.0.2

Nothing has changed except all fields are blank when I enter and the pw manager is also blank. My passwords and logins under TOOLS is still full.

What happened? I did NOT change any pw or history settings since yesterday - as a matter of fact, I did not change anything except to enter cookies exceptions.

Thank you.

Hi Mozilla Community,

As of a couple of days ago, I've had trouble with my Firefox Extensions. The most apparent one being ads appearing on the sites I browse (I have the Adblock extension installed and active). The extension that reveals the "dislike" ratio on Youtube only works if I disable and then enable the extension, for each video I watch. My entire extensions toolbar seems faulty as well.

I've attached images to illustrate: - Rakuten just appears as a blank box upon clicking it - Video downloader extensions just appear as a white line (doesn't open at all) - Bitwarden (password manager) says "not available in private mode", even though I'm not using a private window

Any help would be greatly appreciated. Thanks, Matt

just like the title says

and yes I tried every one of these fixes provided in this link

https://support.mozilla.org/en-US/kb/troubleshoot-firefox-crashes-closing-or-quitting

only one i didn't use is hardware acceleration because I just wanna use Firefox normally I am not here for anything that lowers the normal performance I am used to and it's not a real fix

Also Firefox is literally the only thing that crashes on my PC, even other browsers I tried such as Chrome and Opera (both versions including GX) were working just fine, both safe mode and clean installation by deleted the folders in AppData and even deleting everything and updating windows and drivers are up to date, and it still crashes regardless.

Going to %APPDATA%\Mozilla\Firefox\Crash Reports\submitted doesn't show me Submitted folder which I assume it happened cause of the multiple clean reinstallation I did but there is pending and events and idk how to share a dmp file here.

Only reason I am still sticking to Firefox is the fact that it's more private than say Google, Opera and Edge and that's most important to me, and the problem happens to probably any website, maybe mainly media sites like Twitch and Youtube but it may jsut be coincidence or maybe cause I stay on these for longer than 5-10 mins normally so they are more noticeable.

Thanks in advance, I am surprised not many people mentioning these problems on the internet but I did see some Reddit posts i wonder if not many people are being affected or just that there are many other options for people to bother complain nowadays and I don't use social media much to post there but I may have to do it eventually if it reaches anyone who can fix this.

Suddenly the backgrounds to many Firefox screens - browser, history, settings - changed from white to black. This makes it very difficult for me to read whats on these screens. How do I change them back to white?

The browser screen was black and I did that "about:config" thing and toggled the "browser.proton.enabled" to False which converted the background of the browser to back to white but all the other drop down menus are still black. The bookmark toolbar menu is black, the background of the hamburger menu is black, and the "customize menu" background is black. These areas are now difficult for me to see.

When FF developers start fooling around with colors in the FF browser they need to tread lightly and be aware of all accessibility problems their users may have. Where accessibility is concerned, one size doesn't fit all. Some people have problems with white backgrounds and others, like myself, have problems reading screens with black backgrounds. One simply MUST be aware of sight problems in users.

P.S. I tried uploading photos of the black backgrounds in question but the upload wheel just kept spinning. The photo size was within accepted parameter. Also, I tried to check the box "Email me when someone answers the thread" but that wouldnt work either.

Bing somehow auto default set as my search engine and i need google as my default. when i drop down menu to change it gives no options, it only says "a browser" with Firefox logo next to it. i need help to fix this issue please! tyia:)

I've been using Elijah Lopez's Matte Black (Red) theme for months. Recently, I think because I added the ClearURLs extension or some other change, certain websites enter some sort of "dark mode" when accessed.

Websites that do this include Twitter, an independent blog, and Youtube.

The website appears normally with the default light theme enabled. In the second photo, the website appears in the "dark mode" with the black Firefox theme enabled.

I have deleted cookies and cache, reinstalled Firefox, and reinstalled Extensions. I think this problem only occurs with dark themes, and nothing else. The moment I change to dark theme, the problem comes back. It is strange because the dark theme was working just fine for months until recently.

How can I keep the dark theme, preferably the same Elijah Lopez's dark theme, while using websites normally and not in this weird "dark theme" style adaptation?
