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 find that when I click on links to take me to website through my email in Thunderbird that I will get an error message that reads "we could not verify the certificate, reason=wronghost"

But, if I copy link and copy into browser it works fine. There is a break in the Thunderbird email to the browser. This does not happen with all links but there are about three or four that I get regularly where it fails.

I have talked to a tech guy and we have tried different things and it always comes back to a break in Thunderbird email.

How do I fix this problem?

Thank you, Monica

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 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.

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:

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?

Just began after using the site a couple of times, but I did not indicate or click a setting on the Etsy site to ask for this.

All solution suggestions seem to be for pop-up ads, and don't work to block a website. Is there a way to block this?

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

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!

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).

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.
