Whenever I save a webpage, it says failed in the Download history. The page actually does save but shows it as failed. If I double-click on the "failed" page in the Download history, the download history says that it saved, but if I open the re-saved page the re-saved webpage many times looks like a non-html page or simply only saves part of the page. This is puzzling in that if I ignore the false message that the page failed to save and open the page from my download folder, all looks fine. Please help, Thanks, pianotech

The background colour in the task bars for my Firefox and Thunderbird programs suddenly "inverted" (what was dark is now light and vice versa). Was this intentional on the part of Mozilla? Could it be an indication of a virus or other security threat?

I have tried several times to create a list for the groups I belong to so I don't have to type each name each time. I've had no success in creating this list. Please help...I have groups of over 50 at times and it is a pain without a group list. Thanks for your help

I recently updated and now the settings and quick links tab on the homepage wont work. I have restarted 3 times and tried to reinstall firefox and still no luck. Looking for suggestions as what i should do next to solve the issue.

I am writing second time because something bugged and 10 mins of my text is gone...

Is there a way to stop video on page faster than rmb on every video and then controls and then when play/pause button is visible with other info like video lenght lmb on video to pause it? Like forcing browser to show video controls like this on every video on a page would be really nice because i often show controls to check how long video will be. Shouldn't it be like on youtube where you can see video controls just by moving your mouse over it and it auto dissaper after you stop moving it? Also there is really annoying bug or something, sometimes videos won't auto pause when i scroll down, and on pages with infinite stuff like 9gag it is really troublesome, you have to rmb then controls then lmb to stop it. Prevent videos from auto playing setting isn't working at all.

Tried reinstalling Umatrix and looking at the customize menu but its not showing up there either (restoring cutomize defaults doesnt help either). All my other addons show up just fine. Not having the Icon makes giving temp rules for sites pretty annoying.

Thanks

The last version of Firefox is making some connections I don't know how to stop. I've modified some of the parameter in "about:config", but there are still HTTP request to the following URLs that I didn't manage to stop:

https://firefox-settings-attachments.cdn.mozilla.net/security-state-staging/intermediates/* https://firefox.settings.services.mozilla.com/v1/buckets/monitor/collections/changes/records

Also, does anyone know if there is a configuration file where I can modify directly all of the parameters I changed in "about:config"?

Thanks!

I would like to sync my phone contacts with a file on my linux box. In that way i will be able to edit the file on the pc to look up or enter phone numbers that will be on the phone.

in a rational world, i would go to setup, select sync to file, accept the default of documents/firefox/phone-sync.txt and that would be it. is it possible in this world at all?

Hello. After a reinstallation of W10, I imported in Firefox the file "bookmarks.html" that I saved before this installation. Usually it works very well, but this time, there are no more bookmarks in my menu after the import than before ! It looks as there was nothing in my file Bookmarks.html, however I am sure that this file is complete because I verified it in Excel (.csv). What happens ?... Thank you by advance to the community !

When I try to print a document, including from your frequent questions site, the right and left margins are equal to 1 3/4 inches even though on the web site the margins are set at .5 inches. I have tinkered with all the available options but no matter what I do the result is 1 3/4 inch right and left margins.

This also happens when I try to print a document from Vanguard's message center.

How do I resolve this matter

Firefox was working normally earlier in the day. I'm not aware of any updates on my computer. I didn't install add-ins. When I click the firefox icon to launch the program, the cursor momentarily has the hourglass symbol then nothing happens. There is not error message. Firefox is not shown in the task manager list. The firewall has mozilla firefox in the list of allowed programs. I've tried rebooting, reinstalling, the refresh tool, deleting appdata files, temp files, anything I could find in the registry with mozilla in the name, then rebooting again then reinstalling. I don't want to go back to Chrome... =(

Hi,

I am using FF for my automation testing.I run lot of FF instances/windows in parallel. For example if I run 20 window in HTMLUNIT-Driver then my cpu usage is only 5 to 10% but if i run 20 FF headless then my cpu usage is 80=90% .

I tried FF 80 . Still same behaviour

Stackoverflow question : https://stackoverflow.com/questions/57935905/selenium-firefox-69-high-cpu-usage-java?noredirect=1#comment102532709_57935905

question :

Do we have slim version of headless FF which will use less cpu like htmlunit driver . If not how do i optimize FF so that it uses less cpu like htmlunitDriver

Hi,

Tried to find the solution but the problem boggles me.

I'm using the latest version of Firefox on Windows 10 (2004). Using one Windows session (let's call it WS1), my profiles (even new ones) are extremely slow, as if I had a really bad Internet connection (but responds well to typing or opening new tabs or operating in general, just slow navigation). I have a backup browser, Opera, that works just fine. On another Windows session (WS2), Firefox works just fine, even with the profiles from WS1.

Safe mode doesn't resolve anything.

It can't be a driver problem, as it's the same PC, shouldn't be a software problem, same reason, and both sessions are built pretty much the same way.

I tried uninstalling Firefox, using Windows Disk Cleanup as per this solution https://support.mozilla.org/en-US/questions/1219670 then reinstalling it again and no change.

I can't use the other Windows session as it's not mine, and I can't create a new one either.

Any help is greatly appreciated.

I am no longer able to repost articles directly from websites on facebook. I can only post the urls and wait for a preview to load. I administer an education page so this is becoming time consuming.
