Firefox-Hilfeforum

On a couple of websites, but in particular Rogers.com, the captcha just never ends. It asks to click on all the bicycles, I click on them one at a time until no more appear, hit verify, it brings up something else. It will do this dozens of times and just never ever end.

Switch over to Edge, does the same. Switched to chrome and it works fine. Has google done something to captcha to deny it working on other browsers?

I have checked to see firefox is up to date and it is. I have disabled all extensions/addons. I have run malware/virus scans. On the Rogers community forums there are all kinds of people having problems but there are no solutions on how to fix. Oddly (or not) the problems are similar...captcha won't work on Edge, Firefox but will work on Chrome.

After updating to version 121, the cursor theme, while having it on the window, changes from the default one (Breeze) to Adwaita while also getting like 2x bigger. How do I change it back to default theme and size?

Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?

One of the websites I use now gives me the following error: Please unblock challenges.cloudflare.com to proceed Microsoft edge does not have this problem, but I don't like using edge. I used my search and found many causes. I did the following: Went to my firefox settings and cleared cookies and history I ran two security programs, bitdefender and maleware bytes I still have the problem.

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

Firefox use 100% of my cpu and drops frames when playing 8k video (gpu acceleration setting is turned on). Chrome instead have no frame drops and does not use 100% of the cpu.

I tried to google it and use some solution, but no effect in my case.

PS: 1st picture firefox, 2nd chrome.

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

I am trying to block myself from checking on my old employer's website, and I need to block myself from being able to go to their web page. How do I block a specific website? I do not want to access this site, and I find myself checking the site. I sound nuts, I know. But this is for my own good.

Firefox displays text on the .xml page as html code instead of rendering is as normal text. The layout and images on the page look as they should.

There is nothing wrong with the page, as it is rendered perfectly in Chrome.

In addition, this page doesn't display at all on the phone. When I click on the link it asks me to download it and then asks me which app I want to open it with - instead of simply rendering the page.

I have seen some old threads on this topic, it looks like this issue haven't been resolved for few years.

My question is not just about fixing it in my browser but at the root cause. This page is the RSS feed of my podcast which many people want to access and many use Firefox as their browser. Unless I tell everyone to use Chrome instead.

Can someone help? thanks.

I see where other people have posed this question but the procedure offered is not available to me.

I am using Firefox (Flatpak) version 121.0 on an Ubuntu 22.04 laptop.

On installing a new extension I should either see the extension's icon on my toolbar or else have a clear means of adding it. I have neither.

Clicking on the jigsaw icon in the toolbar, I get migrated to the about:addons page. On clicking the Extensions tab, I get the screen listing all installed extensions. Each extension has a ... icon beside it. But when I click on this, there is no "Pin To Toolbar" option.

What is wrong here ?

In the about:profiles page I can see that the Root Directory for my current profile is: /home/username/.mozilla/firefox/no9r1iq5.default-release-1681391696978 When I click the Open Directory button it does nothing. When I manually navigate to /home/username/.mozilla/firefox I can see that there is no folder there called no9r1iq5.default-release-1681391696978

The Local Directory is show as: /home/username/.var/app/org.mozilla.firefox/cache/mozilla/firefox/no9r1iq5.default-release-1681391696978 This exits and opens with the Open Directory button.

If I search for no9r1iq5.default-release-1681391696978 in the file manager, I see that there are two folders with this name, on at the Local Directory path shown above and the other at: /home/username/.var/app/org.mozilla.firefox/.mozilla/firefox My assumption is that this is actually the Local Folder (it contains files with today's date)

My question is, why does about:profiles show the wrong path for the Local Directory or why is the actual Local Directory in the wrong place (it appears that the path shown in about:profiles is the normal default location)?

I tried creating a new profile and it was created in exactly the same way: the Local directory path is: /home/username/.var/app/org.mozilla.firefox/.mozilla/firefox but about:profiles says it is: /home/username/.mozilla/firefox

I would rather have my profile in the normal default location but I want to ensure that I don't leave pointers to the wrong location that could cause problems.

I am running Firefox 121.0 (64-bit) from flathub on Debian GNU/Linux 12 (bookworm).

Any help appreciated.

I've always liked the Firefox New Tab page, with Pocket, and until today, DarkReader plugin has always worked. But now it says that it can't because the page is protected.

I tried the solution to use bookmarklets, suggested in https://support.mozilla.org/en-US/questions/1350781, but it didn't have any effect (https://sanketmehta7.github.io/DarkMode-JS-BookMark/

If I can't find a solution, I'll just ditch Pocket, and use Google as my first page, or something. Or maybe ditch Firefox, which doesn't seem to think that dark mode is important. I don't like being blinded by the light.

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.
