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,

Hello,

I have a problem retrieving my favorites/bookmarks. I changed computers (all of them, even the hard drives).

I would like to recover my favorites/bookmarks but cannot do so because I am asked to look for them in folders that I no longer have, because they are on the old computer.

Does Firefox not save any information about my favorites/bookmarks? Have I lost them all? Do I have to redo my whole life?

Sincerely, Shinsengumy

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

Firefox seems to be hanging up my computer every once and awhile. Why I think FF, if I am able to kill it with task manager- all is well. Prior to that system is pretrty much locked up, sometimes can't even get task manager running. Also, about twice a week I get a message from FF about oops your Foxnews tab has stopped., please send report. I haven't sent report, just do a reload.

I have run 3 virus checkers, chkdsk and sfc /scannow and all are okay no virus, disk or system files missing.

Thinking of switching browsers for awhile?? Then seems there is a place in profile that has passwords, but I forgot where. Maybe I could download a completely new copy of firefox and keep my profile?? Then again maybe my profile is messed up.

Any suggestions the best way to get a completely new copy of FF??

On Windows 10 current release and now FF 119.0. Down to using Flagfox, Malwarebytes Browser Guard, tab reloader, undo close tab, web threat shield (webroot). Was for years using Noscripts, but stopped it for the last few weeks. Actually I stopped Malwarebytes Browser Guard, web threat shield and noscripts and still got hung up. That only left Flagfox, undo close tab and tab reload running as addons.

Windows 10 volume slider stops working after every firefox update. Have to restart windows 10 explorer to make it work after every login. It will start working again on it's own after the next windows update until I click on the firefox update again.

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.

We have 2 desktop computers, both on the same wifi internet wireless network. On 1 we can ad the Ublock Origin extension no problem. But except for only 2 times, the other computer says installation aborted because add-on appears to be corrupt. Like I said, we have gotten it to load twice but both times it disappeared and now it won’t load. I’m not sure how it can be a connectivity issue, since they both access the internet from the same source. Is it that the problem system has Window 11 and the other 10? Why would it install twice and then disappear? Note that as a test I have uninstalled Ublock and then reinstalled it no problem on the Windows 10 machine. Does anyone know how to fix this? Thanks.

Whenever I download a file Firefox downloads two of the same file. One is an empty file and the second file is the right size.

Example: I want to download a file called blender-4.0.1-macos-x64.dmg, when I start the download the first copy shows up immediately in my download folder called blender-4.0.1-macos-x64.dmg with zero bytes but another one is still downloading. Once that one is fully downloaded too I have another one in my download floder called blender-4.0.1-macos-x64-1.dmg.

Not sure how to prevent that, it is very annoying

There is an app of my PC to open a digital version of the USA Today paper as well as other newspapers owned by Gannett. This app has always run well on Firefox. But a few weeks ago, when selecting the option to print an article, multiple pop-up screens began displaying. It is normal for the article to display in a pop-up screen just before printing but not multiple times. And every time I print an article the number of pop-ups increase... the first time twice, the second time three times, the seventh time eight times, etc. If I open the app using Chrome this does not happen.

See the attached .gif in the past could I use a "mailto:" link without problems, I used this extension: https://addons.mozilla.org/de/firefox/addon/outlook-com-mailto/ But even, when I deactivate it, does it NOT work. As you can see in the gif, the website opens and the mail does not load. usually it should create a new empty email ready to send. I tested it with gmail (because I have a gmail accunt through google) and that worked.

So there is some problem with outlook, this does happen on every page, tested also with disabled adblocker (ublock).

I'm having an issue that has been going on for some time now and it finally has me at wits end. My Account sync keeps disconnecting where I have to go through the sign in process again and again. I have searched multiple times for this issue and have seen that others have suffered from the same issue with no clear solution to the problem. I have now tried with several Firefox desktop versions including my preferred browser being Firefox Unbranded, and every single one disconnects me several times daily.

Does anyone have a solution to this issue?

I frequently visit Facebook and go through a selection of friend suggestions. I don't have time to go through them at the moment so I prefer to highlight select each one with my mouse and copy and paste them to my email.

But because Facebook I presume is using lazy load, as the slider moves to the next slide of profiles it eventually stops because eventually it gets to where profiles have to load due to me now going to that area of the html elements, and now i hate to wait until they load to then re-hightlight and select each one of a continuous pattern which is very annoying

I'd rather be able to just have the webpage that I'm currently on of facebook to have everything load at once, so I don't have to wait for new profiles in the selection to load, when I scroll, or press a button for next list

The image I provided will visually show what I mean I get a selection list of suggested profiles to befriend on Facebook but eventually of either clicking on the right arrow button to slide over to next list to next or by highlight selecting eventually the sliding to next list stops due to the next list of profiles not loaded yet

The second image will show what was once white because it hasn't loaded yet now has

But thats just it I don't want to wait and have to scroll, or click a button and wait for the next batch of elements in which this case is image and link of their picture and name.

I want all those elements to load at once! So I don't have to wait for it to load after I reach that destination on the HTML.

Javascript. Firefox. HTML.Extension?

Whatever you can suggest please wither it be adding a script, changing something of firefox, doing something of html, or adding an extension?

Is there a way to enable using both a default pattern as well as a custom image for the background on Firefox Color? I really want to enable both but it is making me choose one or the other. Please help me do this or enable the ability to do so.

Hi,

I find the new(?) "Firefox View" quite helpful but...:

I have two firefox desktop installs and one on my phone. My foxes are all set up to open with the tabs from the last session.

Expected behaviour: "Tabs from other devices" shows all recent tabs from all 3 devices (minus the current one of course).

Actual behaviour:

• On the desktop firefoxes, under "Tabs from other devices" I only see the FF-instance from my phone. Missing the other desktop install (see attached screenshot).
• On the phone, I only see the most recent desktop instance.

It seems like as if it either can handle only one mobile and one desktop install or it hides devices not currently active?

Thanks for clarifying and/or fixing ;-) Sören

I have some javascript bookmarks (basically they just insert the current date in an appropriate place in the URL and then open it. Example at the bottom).

Both just clicking on these bookmark or left clicking and "open in new tab" or "open in new window" works as expected, that is,

• the computed URL is displayed in the address bar
• and the page is displayed.

So, fundamentally the javascript bookmarks work as I expect.

Now my problem: If I put this bookmark in a folder (either alone or together with other bookmarks), left click on the folder and select "open all bookmarks" it will open a new tab for each entry and the normal bookmarks are loaded in the tab as expected. But the tab corresponding to the javascript bookmark opens, and

• displays the javascript code (and not the computed URL)
• shows a blank page

What do I have to do that "open all bookmarks" also execute the javascript?

Example bookmark: javascript:function%20url(){%20%20%20%20%20%20var%20date%20=%20new%20Date();%20%20%20%20%20%20var%20y%20=%20date.getFullYear();%20%20%20%20%20var%20m%20=%20date.getMonth()+1;%20%20%20%20%20var%20d%20=%20date.getDate();%20%20%20%20%20%20if(m%20<%2010){m%20=%20'0'%20+%20m;}%20%20%20%20%20if(d%20<%2010){d%20=%20'0'%20+%20d;}%20%20%20%20%20%20var%20date%20=%20"/"%20+%20y%20+%20"/"%20+%20m%20+%20"/"%20+%20d;%20%20%20%20%20%20return%20'http://www.gocomics.com/calvinandhobbes'+%20date%20+'/';%20%20}%20window.open(url(),"_parent");

Lately, far too many websites I try to open, simply won't! Sometimes it's via links from my home page, sometimes it's links within various websites, like a newspaper, or social media, just whatever, no rhyme nor reason, nor consistency. Even when I manually input the url, nothing happens, the browser just sits there, nothing happens. I've restarted, I've refreshed websites, clicked on "open in new tab/window", nothing gets it to work.

I've noticed for awhile that files I've opened to view were being automatically downloaded into my downloads folder, but I haven't investigated it until now. I found out this goes back to 2022! My downloads folder is cluttered with files I only wanted to view and not save. All the previous forum questions which I've viewed have now been archived, so I'm opening a new one. On one of the previous threads, I found that a new hidden setting was added so we could change this back to the old behavior of the automatically-downloaded files going to a temporary folder instead of being saved in our downloads folder. We can use about:config to find browser.download.start_downloads_in_tmp_dir and toggle it to "true."

Instead of our having to dig around on the forum to find how to change this, the setting needs to be added to the Main settings page under "Downloads." Then those of us who wish to "always" be asked where to save files will be able to find this setting and change it to our preference. If I want to download something to keep, I will intentionally save it. If not, I expect anything I read online to remain in a temporary cache folder and be deleted when I clear history (which is when I close Firefox, because that is what is selected in my settings).

Please unhide browser.download.start_downloads_in_tmp_dir and add it to our main Settings page. Thank you.

The attached picture is a screenshot from the thread where I found the information about this setting.

I'm using last release Firefox in a fresh install of Debian 12 with KDE. Trying to personalize colors and get a coherent style, I've installed Firefox Color and it worked fine, except for a few GUI elements.

But this is a little more than merely cosmetic. The save (and open) dialog is very different from those provided by the WM. (kwin)

They need double click to navigate through folders and the subfolders don't get grouped before the regular files. Also the appearance is different both to KDE widgets and to Firefox theme.

Is there a way to show "native" dialogs or at least to customize them to be more similar?

TIA,

 Nico
