Firefox Community Forum

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

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.

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

Starting this morning I suddenly cant delete or mark emails as read in Outlook.live.com. Even if I open an email, and it appears as read after that, if I refresh or leave the page and come back, its marked as read again.

I tried dropping all add-ons (a kill switch to drop all add-ons and re-activate them is still a feature I feel Firefox needs, I have to click every single one of them every time) to no avail.

I was in the process of writing this question on the Microsoft forums (which is usually like whizzing in the wind) when I thought to try a different browser. I had zero issues and Outlook.live.com worked perfectly normal on Microsoft Edge.

This HAS to be a bug in a recent update in Firefox

Had it yesterday, happened this morning after the restart and just NOW, when I entered 6 lousy tabs, and they are NOT in the recently closed list either.. wups, gone, no tabs, setting has a check mark on open previous windows and tabs. Within 24 hours, lost the tabs three times with a non reported crash and Firefox closing itself with no warning.

I honestly do not think I am responsible to keep a backup of my browser history, I expect a browser to do that. I switched from Opera to Firefox not to long ago.. even Opera is a security risk.. at least it doesn't delete your tabs just for fun.

Very simple.. that happens once more and i am OFF this browser....

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Firefox for Linux has a bug where it is unable to drag a tab from a non-active window. As in, if the window focus is on Firefox window A and I try to drag a tab from Firefox window B to window A, I have to click first the window. I can't just intuitively drag the tab from a non-active window, because it will get ignored. It will just activate the window, ignoring the drag.

Firefox for Linux, running on Nobara KDE latest desktop. Confirmed also on KDE Neon latest desktop.

When I right click on an image and select "save as", after selecting where to save it and then selecting save, firefox just hangs and is completely unresponsive, leaving me having to terminate it through task manager. No error message ever come up, Firefox just freezes.

Hi all Firefoxers,

There are a few sites that I always access via a URL that could look like :

https://device.domain.com/admin/

When I went to visit that device, typing in the URL bar "device.domain..." , Firefox's 1st default suggestion shows as https://device.domain.com/

The problem is that I never visited that site, the way to access this device is https://device.domain.com/admin/ - there's no way to reconfigure the device and have an auto-redirect to .../admin location.

https://device.domain.com/ is not in my Browsing History nor do I have an open-tab. In the settings Privacy->Address Bar, disabling "Browsing History" removes https://device.domain.com/ from the suggestion list but it also removes all suggestion from the history. This is the expected behavior, the bug required fix isn't related to this.

If the "Base URL" isn't saved in the Browsing History, how can someone tell Firefox to only suggest absolute entries from the history?

I set up a website for my wife a while ago. Most recently we noticed that some (not all) of our pages are not shown correctly when we use Firefox as browser. Specifically, when you open a webpage and scroll down as far as you can, there is a certain white area at the very bottom visible, below the footer. Now, if you wait a small amount of time, then scroll a little up and down again, the white border is not longer there and the page appears as it should.

Example pages for this behavior are: https://praxis-weinhold-schattentherapie.eu/entspannung/ https://praxis-weinhold-schattentherapie.eu/praxis/ https://praxis-weinhold-schattentherapie.eu/ueber-mich/

It is not happening e.g. with: https://praxis-weinhold-schattentherapie.eu/unterkuenfte-und-impressionen/ https://praxis-weinhold-schattentherapie.eu/angebote-und-kontakt/ Example screenshots are attached.

This strange behavior cannot be recognized with other browsers, we tried Chrome as well as Edge. Many thanks in advance for any ideas on how to adress this! Best regards Carsten

Whenever firefox has multiple tabs open and on any single tab youtube is running i find youtube to crash lag and even crack itself by audio playing with struck video. FYI the same issue is not experienced in other browsers like brave for instance . I hope you provide attention to this problem and solve this issue as soon as possible and as I mostly use firefox to browse and use its dev tools.

There is a problem logging into Disqus. (disqus.com and disquscdn.com)

This is affecting Linux and Windows installations.

Page I'm having problems at www.lawyersgunsmoneyblog.com

I have used the troubleshooting mode and caches have been cleared and all extension disabled with no luck.

Other browsers are functional. The log in doesn't appear at all:

Is it possible to combine history/bookmark files? Firefox has truncated my "History" to 15 days and the only option I see to get elder entries is to combine a backupped history file with the current one. An easy-to-use tool for this task would be welcome. I did not change my config options after the update to 121.0.1 (64-Bit) (Windows 10pro) but I think I had the total history (from years) before the update. My current Options related to this topic are: browser.history_expire_days false places.history.expiration.max_pages false places.history.expiration.transient_current_max_pages 501234 privacy.clearOnShutdown.history false privacy.history.custom true history (*) Boolean Number String

I already sreened Help files of this Forum concerning lost history data but they all do not give sufficient answers or I do not understand them (as a German user). Thanks. Martin

Firefox won't play YouTube videos. I've tried everything. There seem to be plenty of problems on the forum BUT NO SOLUTIONS!

I'm ready to switch browsers - permanently!

Is it still possible to configure userChrome.css to have the URL field in the Firefox 'Add bookmark' window? Also, is userChrome.css configuration going to be used no more in future releases? If yes, then how will we be able to customize, for example, fonts in Library, side bar and context menu?

Hello,

I have a platform where architects can download digital content in the file formats of dwg (autocad) and ai (adobe illustrator). The site is old and has been working for many years.

Today I received an email from a user that had issues downloading the ai files. I went on to the site an investigated. I am also unable to download the ai files. The dwgs are working as expected.

The ai files are converted to pdf and open in the browser in some web preview. If I then download the file from there it is still, when downloaded to my machine, a pdf. This is not the behavior from before. This is a change in Firefox.

How, when, and why is this change implemented? It seems like a pretty radical change, to coerce one file format to another without any option to get the source file for the user.

Any help is appreciated.

Getting to www.costco.ca impossible during past few days - disabling tracking does nothing! Tried relaxing most security and tracking settings, still no results. MS Edge works just fine, like Firefox used to until now. Guess it's time to switch if no other option.

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.
