Diễn đàn hỗ trợ Firefox

Hello team,

            I've implemented passkey (webauthn). All browsers working fine along with firefox for regular passkey But we implemented ROR (well-known/webauthn) for cross domain using rpid (https://web.dev/articles/webauthn-related-origin-requests). Only this is failing for cross domain passkey in firefox where other browsers working good. I am using firefox version 140.14.0. I know its bit old but just asking does it support? We've some limitation so not able to test latest version of firefox. I am getting below error in console

"A resource is blocked by OpaqueResponseBlocking."

Any help regarding this will be appreciated.

Regards! Sourav

I had an automatic update to my Firefox browser desktop yesterday to version 155.0. I didn't notice any issues at the time, but that was because I was using my bookmarked websites rather than looking up anything on the search bar. My keyboard input worked just fine and I had issues.

Just now, I was tried looking something up on the Firefox search bar and it seems that nothing I type into the Firefox search bar worked. I can't use commands either, I tried to copy paste and it didn't work.

im trying to restore a session that i accidentally closed. i deleted the sessionstore.jsonlz4 file, copied and pasted the upgrade.jsonlz4-20260715202819 file, and renamed it to sessionstore.jsonlz4. In the new window, all the tabs that were supposed to be restored have been replaced with moz-safe-about:blank tabs. The tab group where i had several tabs is still there on the tab bar. What did i do wrong?

After updating Firefox to the latest version, my bookmarks are no longer syncing across devices. I have Firefox installed on Windows 11 and Linux, and the sync was working fine before the update. I have tried signing out and back in to my Mozilla account but the issue persists. Any help would be appreciated.

I have bookmarks saved in folders on the Bookmarks Toolbar, when i open the folders the list is drop down as usual but using the mouse wheel is too fast. I recently adusted mouse settings in about:config for smoother scrolling on webpages. Is there a separate mouse wheel setting for the bookmarks?

is there any way to contact someone from actual support about reporting/taking down an obvious spam bot account? i have an old post in the connect forum that i can no longer access (my email has changed and it didn't connect to my account for some reason). this bot account is responding to the post with spam messages: user byt434t. looking at their other responses shows nothing but similar spam messages.

i have already reported the messages to moderators but that might be myself (who can no longer control that specific account regardless).

much appreciation for anyone who can rectify this issue.

attached is one of the messages responding to my own (old) user profile that i cannot access.

How to get rid of BING setting on internet/Firefox

Contributor note: See also /questions/1595954 and /questions/1595955.

When I click on a PDF link it will auto download the PDF but then if I click on the same link again it opens it inline. I want it to always open inline and if I wish to save it I'll manually do that.

I've looked around and I found this that mentions using browser.download.start_downloads_in_tmp_dir and browser.download.open_pdf_attachments_inline. While setting the downloads to be in the tmp dir is nice for not clogging up my downloads it still doesn't solve the issue of opening and not saivng. The setting for opening pdf attachments inline sounds like it should fix it but still every time the first time I click it, it starts downloading it.

Is there any other setting that could stop this or some reason why those settings might not apply in all situations?

title sums it up mostly. I've entered troubleshooting mode; no discernible difference. When I switch profiles the issue is resolved even with the same YouTube account. Tried clearing the cache, nothing. Most recent version of Firefox, windows 11.

Pressing print/pdf button for screenshot then pick the folder destination documents then press save and what it's used for is decrease the size of the screenshot with pinching the screen then retake the screenshot of desired smaller size however for the first time it has an error in documents folder the says "can't open pdf" and then I tried the 3 dot menu in upper right corner to use an app to open it up and I went through all of them and nothing works

I have personal files on rapidgator.net & premium account. if i try to download one of this files on firefox my speed is only 2-4Mb/s if i try to download with JDownloader the speed is 45-55Mb/s (one single file) This has been happening since October 2025...
