why do you stalk and bother the users? i do not want to update! without warning you alter things i do not want you to alter. you take things out so people have to use risky 3rd party addons.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Is there a Firefox setting that automatically clears cookies? When I turned my computer on, it had been cleared of cookies since the last time I had it on a few hours ago, but I didn't do it. No one else here to use the computer but me. I don't want cookies cleared automatically. How do I change it back to manual? I use Firefox Browser 120.0

thank you

From the main opening screen on the right hand side ( Pic1 ) click on the three horizontal lines Tab. Go down to "Bookmarks" listing (Pic2) Click on " Bookmarks " to open and it gives you Pic3.

At the bottom of Pic3 is " Recent Bookmarks " and it lists ALL the previous bookmarks that have been opened.

Question - I do not want that list displayed, How / Where do you disable it in Firefox ?

Other people who have posted this question have had individuals just saying " Right click " on the bookmark and delete. That not only deletes it from the recent bookmarks list BUT also from the Actual Bookmarks!

So.... not a good idea.

I have spent over an hour searching the internet and the Firefox settings trying to figure it out.

Please help. Many thanks David

I was required to make a quick computer switch. I cannot access my old computer. When I opened Firefox on the new one it was without my bookmarks, saved passwords etc. I really need those passwords. And I don't like an orphaned window for Firefox floating around with my info. At best, how do I get it on my new computer. At worst, how does the info get deleted so that it is not available online to anyone?

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

For the past few weeks (perhaps after updates?), my Firefox browser has refused to connect through AVG secure VPN - it is completely blocked and time-out on ALL websites. When I disconnect the AVG VPN, then Firefox works immediately correctly. It happens on both private and public networks.

Both Firefox and AVG secure VPN are up to date. Firefox 120.0 (64- bit) AVG Secure VPN 5.28.9117 I have been using AVG professional antivirus and firewall for years. Windows 10 Latest Version.

Any suggestions please?

I saw there was a fix / workaround for pasting text into WhatsApp on desktop in Firefox, but I used to be able to copy and paste images too and that still doesn't work. It works in the AVG secure browser though. It used to work in Chrome, but I don't want to go to Chrome just to send a picture from my desktop. Is there any workaround or fix in Firefox to copy and paste images into WhatsApp on desktop?

I typically download 30 to 40 video files daily of around 5 MB each. The most I can download seems to be 8 files, then I have to select the next 8 to download. Is there a way I can select all 30 files and have them download one at a time in order without having to keep selecting the next file?

Lately, whenever I click on a file (be it PDF, XLS or whatever), it doesn't open. Instead, I see the relevant app (Acrobat, Excel, or whatever) flashing on the taskbar and I have to click on it to view the downloaded files. Not a big deal, but it used to be different, with the relevant app opening a window with the downloaded files (which makes sense: if I click on it to open - and not download - I want to see it now). Does this happen to you as well? I could not find any option to control this behaviour, and I don't think it is intentional.

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

I have the e-edition app for my newspaper on my PC. This allows me to read an electronic version of our daily paper. One feature of the app is to be able to print parts of the paper such as the crossword puzzle. When selecting to print the selected section, the section displays in a pop-up which it should. However recently when using Firefox the pop-up displays twice. And when printing again, the pop-up opens three times and then four times and then five times. I can get it to print ok from the last displayed pop-up and then I just have to close all the other pop-ups.

When using this app with Google and Edge this does not happen so I was wondering if there is a setting in Firefox that needs to be changed. Turning off pop-ups doesn't help in that I get the same of screens displayed telling me pop-ups have been disabled.

This odd behavior only began a few weeks ago.

Thanks, JB

Dear Support Team,

I always receive popup messages when trying to play a youtube video. "Ablockers not allowed". But I haven´t installed any adblocker. I am not sure, but I think this erreor occurs since the last Firefox update (?). Had never before this error. See file attached (in German).

I am using Windows 10.

Thank you in advance for your help ! Best regards Chris

Firefox has been crashing multiple times per day for several weeks now. It used to be fine, hardly ever crashing. I can't think of anything I'm doing differently since before the crashes started. I can only assume that it started after a specific Firefox update. I do have a lot of windows/tabs open at once, but that was never an issue in the past. Occasionally individual pages will crash, usually several at once. The entire software crashes all at once regularly as well. Sometimes the crash seems to cause other issues, such as my computer hanging up for a bit, or my monitors going blank and the graphics system seeming to reset, before Firefox actually crashes. I don't always get a crash report dialogue when the whole thing crashes.

Most recent crash report ID: bp-bd37576c-c5ef-419f-a031-fe1910231123

I keep my Windows and Firefox up to date. I tried turning off hardware acceleration, but I think that might have made it worse so I turned it back on. I cleared the caches (which took well over five minutes), and ran speedyfox a few times. I exit Firefox through File > Exit whenever I need to restart or run other heavy software.

When I have to change a setting on my LAN printer, an HP, I should be able to access its built-in settings module. Firefox will not let me access the printer because it doesn't have a trusted certificate.

So I get a blank page with the message: "we could not verify the certificate: reason = untrusted" and doesn't give me any options. In versions past, I recall an option to connect anyway if I trusted the site.

If there is a setting that lets me enable the option to continue anyway, where is it? Alternately, is there an exception list, perhaps by IP address, that will allow the browser to connect? Perhaps another solution?

I can't be the only one who is encountering this issue.

Thanks,

Ed
