Firefox Community Forum

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I recently migrated from Chrome to Firefox on my Mac and successfully imported all data, bookmarks etc. However I cannot figure out how to ADD a new bookmark to an existing folder. Every page I read about bookmarking fails to show how this is done. In Chrome its simple since the drop down menu allows the user to view every folder, but in Firefox I don't see how to do this. Furthermore, when I go to Bookmarks>Manage bookmarks I don't see any of my folders..PLEASE show me an EASY way to do this. Thank you

Exported a bookmarks html file from Mac (Sonoma OS) and tried to import it in a computer running Zorin (linux) 17. The file can be found, but when I click it, I am told there are no bookmarks therein. If I open the HTML file it's all there. Full of bookmarks. What am I doing wrong? Thanks for reading.

I am using a Samsung Chromebook Pro V2, running Debian, and installed Firefox using the Flatpak command "flatpak install flathub org.mozilla.firefox". The Firefox icon appears in the Linux apps group and I have opened Firefox using that icon.

How do I get links in my Linux apps to open Firefox and take me to the URL?

Thank you and Happy New Year, Abe

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

I am a Cacti developer and we are considering switching from FontAwesome Web Fonts to Tabler Web Fonts. However, on Firefox for Windows only, we are having a major slowdown when using the Tabler SVG based webfonts. The page load is first stalled by Firefox apparently loading all the Web Fonts, which would appear normal with any browser (though exceedingly slow on Firefox for some reason).

However, once the page is loaded, when going off tab to another browser tab, and then back to the Firefox tab that includes the Tabler webfonts, there is a 3 second delay before the tab switches. When we enable the performance analyzer, we find that the delay is almost 100% Reflow of the page, even though the page is static as this point (no changes) from the last time it was activated.

We do not have this issue on Firefox for Linux, MS Edge or any other Chromium browser, only Firefox on Windows. I'm using the latest version 134. Should I be opening a bug?

Hello, When I view some pages with inline video graphics, I see a garbled video frame. I have attached a screen grab from part of one screen. I have no issues with YouTube or other videos. It's just the graphics of some webpages such as looking at an Apple product on their site. I have not had this issue using Chrome under the same conditions. It's like I have a corrupted Codec or something. Does anyone have any suggestions? Thanks.

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

The first image is with Fx 103 https://i.imgur.com/r9L3MtM.jpg

This next one is with Fx 102 https://i.imgur.com/N8p1gis.jpg

Others having resolutions other than 1920 x 1080 are having the same problem. Any help would be appreciated

Middle click on ordinary text links works as before. But on some pages a middle click on a button shows a vertical scroll up/down icon as when middle clicking outside the button, instead of opening link in new tab.

The problem begun Friday 29 September after I updated from previous esr-version (think it was 102.-something). I have tested on my old Windows 7 PC, and it worked fine before update, but same problem after updating to 115.

I have verified that about:config browser.tabs.opentabfor.middleclick = true.

One example from a free site: https://sok.riksarkivet.se/scb-fodda-vigda-doda?Forsamling=huddinge&Lan=0&DatumFran=1880&DatumTill=1890&Dokument=F%C3%B6delse The green button with text "Bild" is the problem.

Just fund that the green "Bild"-buttons on other pages on same site works just as before: https://sok.riksarkivet.se/?postid=Arkis+eef4e56e-60a2-4221-9c36-8a7a68280d28&tab=post&flik=1&s=Balder

I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

I have a new installation of Ubuntu 22.04 on my 2015 Lenovo IdeaPad 300. I have a new SSD HD 1 TB in size and it should work, however, Firefox keeps crashing. Other apps are crashing too.

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

I installed Firefox years ago. This morning, when I click on the browser icon, I get this message: Error platform '127.0.2' is not compatible with minVersion>= 127.0.1 maxVersion<= 127.0.1

What is going on? The browser updates itself so I don't do anything. But now, it doesn't work. I use an alternate browser to send this message to you.

This morning I noticed that my Firefox history has lost everything before April 2018. Fortunately I have another computer in sync with the first computer, and I was able to transfer the file places.squlite and recover my history. But why did it happen? And it's not the first time. Last year I lost from 2015 to 2017 or so. How can I prevent this from happening again?

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.
