Firefox Support Forum

Currently, there appears to be only one option to tell Firefox to open a given site in a specific container; that is, from the URL bar, to the right.

Would it make sense to have this configuration option presented in "edit bookmark" and/or in a right-click pulldown menu "Always open in this container"?

I noticed the mozilla.org website has a new favicon. I feel like that sort of thing usually alludes to some forthcoming development. Hmm...

My question is. Hmm? I wonder what's going on over at Mozilla.

I just installed FireFox but keep getting Chrome browser. How do I set FireFox as my default browser? My bookmark tab icons keep changing - how to change them back permanently ?

When you switch the language in a text field, the focus on that text field is lost and the focus goes to another browser tab. This only happens if at this time a video is playing in mozilla in picture in picture mode with the Always on top option enabled. How to fix it? (Ubuntu 22.04)

Hello, I'm using a document management system (SeedDMS for those who know) through Firefox 122.0.1 (64-bit, canonical 1.0, downloaded from packages.ubuntu.com for focal, running on Debian Bookworm, kernel 6.1.0-17-amd64/Debian 6.1.69-1 x86_64, X.Org X Server 1.21.1.7, KDE Plasma 5.27.5, KDE Framework 5.103.0, QT 5.15.8, i7-5820K, GeForce GTX 1070).

Within this document management system pdf.js (v4.0.379) is being used to preview/view PDF Documents. After starting Firefox the PDF view inside the DMS works fine until I suspend (to memory) and resume my machine. Regular HTML-content looks fine but the resumed DMS session shows only blank (all white) Pages inside the PDF view. Changing to a different PDF file doesn't help. The number and size of these pages is presented correctly. I can even select and copy (invisible) text from these blank PDF pages. The problem applies to all PDFs, whether they're single or multi paged, have images inside them (like with PDFs from a scanner) or not, etc. Reloading the page/closing reopening the affected browser window doesn't help, i.e. the problem persists.

I recently found out, that this also applies to PDF files directly opened inside Firefox (which also seems to use pdf.js as a PDF viewer), that is, this is not related to a specific site like my DMS.

The problem always persists until I kill Firefox and start it over.

Pdf.js seems to use a canvas inside a div (see screenshots attached) to draw the visual PDF content and another div to make the text layer selectable/searchable etc. I don't know what's happening to canvases on a system suspend/resume cycle in Firefox on Linux, but I suspect that's where the problem originates from.

This problem already affected older versions of Firefox and pdf.js.

Please let me know, if you need further information from my side to investigate that issue.

Thanks a lot!

After facebook messenger upgraded their security chat with end to end encryption call/video is not possible in firefox. Call/video buttons even disappeared. However i can call from microsoft edge web browser for example. Is this some kind of bug with mozilla? Anyone have experienced this too?

I've read all of the recommendation on how to keep links from opening in another window. Tried them all to no avail. This is a new problem. Anybody out there finding the same issue? Find a fix?

Hi jscher2000,

my apologies for creating again a new question: still being unable to reply directly due to the "unexpected error" message.

Thank you very much for your prompt reply.

Yes, following your instructions I now can see and access the attachements. I cannot still opening them, only download them. It is not perfect but at least I can have access to the attachments without having to exit Firefox and go to Acrobat.

Thanks again!.

I have a problem. When I access my Firefox main default screen I open up a respective website I want to access but within a matter of a few seconds the main default screen automatically opens up again meaning I now have two windows open which shouldn’t happen! I have opened up ‘Help’ and have refreshed Firefox a few times now. Additionally, I have opened ‘Troubleshooting Mode’ which comes up with ‘Restart’ then ‘Open’ and I have ‘Refreshed Firefox’ from this option. I have cleared my Cookies and Cache. I asked for help through the Firefox Community. I received one response asking if the problem still happened in ‘Troubleshooting Mode’. My response 'yes' it does but I have not had any other reply. Hence, I am stuck. Nothing has worked which I find very frustrating. I have used Firefox for many years now but if I cannot resolve this matter I will have to select a different browser which I don’t really want to do.

I'm using a Hotspot provided by Cisco in a library and when first connecting to the Wireless network, Firefox prompts me to login to network in order to have Internet access (expected and works fine). However, once the time session expires Firefox will sometimes prompt again to login. When this fails and internet access is abruptly ended, I've to reconnect to the Wireless network and have Firefox prompt to login.

This is a security vulnerability as someone could advertise the BSSID of the router and have victims connect to their Hotspot instead of the true one.

I've been trying to reply to my previous question here: https://support.mozilla.org/en-US/que.../1440060, but my reply ends with an error - c attached. Therefore, I'm starting this new thread.

First, thank you for the answers. I have run into an issue and also have a follow-up question.

Follow up question: A while ago, I changed the autoplay settings in about:config, but I noticed they reverted to default. Do these settings reset with major browser updates? Or could it be that the settings' names changed, resulting in the default value being applied? Should I periodically check these values to ensure they haven't changed?

Issue: I updated the settings in about:config as mentioned in https://support.mozilla.org/en-US/questions/1440060 by cor-el. It appears to have stopped the autoplay of videos. However, after browsing Google News and Yahoo News articles for about 30 minutes, my browser crashes. This happens under the same usage pattern as before. The browser becomes unresponsive, and if I click on anything, I see the rainbow Apple spinning wheel. Eventually, I have to force quit the browser. See attached.

Thank you!

Update 123.0 deleted all my firefox data from logins.json. backup files are corrupted or have no data. No support article suggestions have worked. The .json files indicate that there is data, but appears blank in notepad, and wont load in json reader in firefox

I've been trying to reply to moderator "Phil" who requested information regarding Firefox crashing while on Youtube. When I press "Post reply" all I get is an error message:

An Error Occurred

Oh, no! It looks like an unexpected error occurred. We've already notified the site administrators. Please try again now, or in a few minutes.

It's important "Phil" gets my message as others may be affected my possible Youtube shenanigans. If possible, can you forward this message to "Phil": Unfortunately there are only two reports generated during the problems with Youtube:

The problem caused my system to stop responding forcing me to power cycle to clear my PC, so no reports could be generated. Hopefully these two will show what the problem is. In the meantime, can you check the reply system to make certain it's working properly?
