I'm not very good at English, so I use a translator. After updating to the latest version of Firefox, the problem I'm having is that when I play a YouTube video on the web side, the playback box will have a large white colour, as shown in the red box below. I would like to know what is causing this, my current version is 123.0

I am using Firefox 123.0.0 (rel. 20-Feb-2023) on a Win 10 Pro v22H2 computer.

I understand that FF123.0.0 is supposed to include a new option to "Report Broken Site" on the menu (hamburger icon) that is described in the support article How do I report a broken site in Firefox desktop? but I can't see this new option. I also checked the menu options under More Tools and Help but can't find it.

Exiting and re-opening Firefox didn't solve the problem.

How can I turn this message off? Some sites I visit give me that message, it shows up when I'm typing a reply to something which pushes the page lower and fouls up my ability to keep typing, then if goes away, comes back, goes away ... I just want to kill the message entirely. I'm not worried about speed, there's nothing to fix, I just want the message gone.

Again I had to create a new question because i still get an "Unexpected error" when I try to answer. (By the way I tried all suggestions to fix the error and also reinstalled Firefox but still have the error)

jscher2000 i think you are correct. The blue link in the PDF file is not a web link but a link to the specific attachment. It appears browsers are currently unable (not programmed) to access attachments directly. I tried in MS Edge with the same result. After contacting MS Support, MS stated that they are aware of the issue and that they are working to fix it in a future release of Edge.

Attachments can be accesses in Adobe Acrobat as you described, but it would be good to be able to access them directly from Firefox instead of having to save them and then using Acrobat.

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

After an update yesterday, I found out the password manager integrated in Firefox was completely empty. I tried to rename logins.json.corrupt into logins.json, I tried deactivating all the plugins and I also tried copying the file into a new Firefox profile but it got corrupted right away again. If I put in an old logins.json it works but unfortunately it's a saved file from about 3 years ago.... Any idea about how I could get my passwords back? How to "uncorrupt" the logins.json?

Thank you in advance.

Hi. Is there anyone having experienced similar phenomena?

1) Firefox stops showing Gmail correctly after a few days. Immediately after starting Firefox, I can log-in and open Gmail.com correctly. But after a few days keeping opening Gmail on Firefox, Gmail.com shows error messages regarding Cookie (please see the attached screenshot). If I do "Try clearing the startup cache" from trouble shooting information tab, Firefox shows Gmail correctly again, but after a few days the same issue happens again.

2) Fire fox cannot log-in on Outlook.live.com. As title says, I cannot log-in outlook live. Whenever I try to log-in from Outlook log-in page, Firefox shows log-in page again. This issue isn't resolved by inactivating "Enhanced tracking protection".

Both of them started to happen since the update around the end of 2023, I think. (On the other hand, Chrome works on both websites correctly)

If you have some information, it might help me. Thanks in advance.

I suspect that a recent Microsoft update changed the default browser on my computer from Firefox to Microsoft Edge so everything now opens in Edge instead of Firefox.

When I checked in Firefox Settings I saw that Firefox was supposedly still the default browser. I hoped that by re-selecting Firefox as the default it would take things back to the way I liked them (Firefox as default), but I'm still stuck with everything opening in Edge and am very unhappy about that. I like the greater privacy of using Firefox, and I prefer the way it works.

How can I disable or completely get rid of Edge and get back to Firefox as default browser? I don't like being spied on, and I don't like having my choices disabled and being forced to do something I didn't choose.

If someone can help I would appreciate it greatly but in replying, please bear in mind that I'm a 76-year-old retired carpenter more familiar with hammers than with computers.

I just recently had Firefox updated, and I'm already having problems regarding notifications. When a notification starts up while I'm typing, it takes me out of it and I have to click back in. I had to turn them off temporarily to avoid flow breaking. This never ever happened before the update as the notifs worked perfectly fine w/ no interrupting. I also noticed in the taskbar, each notification is treated like a new browser window for some reason. This may be related to my current issue.

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:

bp-91f496a8-971c-4a87-a642-011d10240220 bp-7d820f6c-dcf9-4cef-bb60-1a9f50240217

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?

My company uses Oracle Fusion as its ERP solution, and I frequently have to download files from Oracle BI Publisher. Prior to V123 of Firefox, which installed this morning, I could click on the file/report in Oracle Fusion, and the file/report would get moved to my Downloads folder. After the update to V123, nothing happens after I click on the file. I had a co-worker replicate the problem after his Firefox updated to V123. Please advise if this is a known issue and if there is a resolution.

This AM, I opened my Firefox Browser for the first time today and attempted to sign into my EaseUS account. I was confronted by a "request" to add "Browsing Safety by Safely" as an add-on to my Firefox. However, it would not let me to skip this "request" without adding it to Firefox. Nothing I attempted worked. I've never heard of a compulsory add-on, least of all from Mozilla! If I would have had the time, I'd have tried different accounts/log-ons/browsers, etc. However, I didn't have the time to do it then. Help please.

What is this? Have you heard of it? Do I have a problem? Should I remove the Add-On?

Thank you.

FF version Extended Support 115.70esr (64bit) I have set /General/Startup/"Open previous windows and tab" - FF does not restore. It worked as expect before I upgraded opsys (Opensuse15.4 to Opensuse15.5).

Please note: I AM NOT TRYING TO RECOVER FROM BEFORE THE UPGRADE! I am trying to get FF working normally (for me) with my usage and history SINCE the upgrade.

After reading https://support.mozilla.org/mk/questions/1407888 I believe I have tried everything there. FF sometimes restores one single historic tab, sometimes it comes with with one single tab opened to my default page.

1) "sessionstore.jsonlz4" did not exist in the main profile dir. (It does not because I followed instructions in the link above to copy it there and try again).

2) I do have a session file, found in sessionstore-backups dir , displayed with this recommended online converter/translater "https://www.jeffersonscher.com/res/scrounger.html"; it shows the expected windows and tabs.

3) Starting after copying the "sess...jsoniz4" file into the main profile dir, I get one window with one tab displayed; I had about 4-5 windows and 15-20 tabs open when I last closed FF, although when doing research, I often have a 10-dozen windows with 100+ tabs.

4) The History menu does not show a "Restore..." option at all. In the window that did open with a historic tab, the History/RecentlyClosedTabs contains a list of plausible sites, about 10, which may be correct for that window. But there were certainly many that were actually open at the time I shut down FF and the window has only opened one.

Thank you for any help here. Rufus
