I cannot access the Epson ET-2850 Drivers and Utilities Combo Package Installer since the time has expired.

I checked and the clock in my computer is accurate.

ftp.epson.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

I used to have an occasional sound problem with FF, usually felt when YT clips could not be heard any more. I mean to remember that it could be fixed (until next time) by restarting the file explorer somewhere in Task Manager - not a convincing solution but one I could live with.

Today, there's a new situation. Again, trigger was the missing YT sound in FF - not in fx Edge, and that the Task Manager trick didn't work (or maybe I restarted the file manager in the wrong tab?). Looking for a solution, I happened to see that the YT mute function in the FF tabs seems to be gone. However, other sounds are affected likewise. Also, I can't see them in Edge either. After various restarts (or maybe something else I did, instigated by the various instructions I found?), the sound is back.

However, while continuing to pursue possible solutions, I also happened to find that my browser is being 'administered by my organisation' - what ever that means (see two annexes). Who did that? I would say, this is not something I did, I would prefer to see it gone. But how? Will the other browsers (which I keep as a spare, and that I'm hardly familiar with) be likewise affected?

This is an equation with too many unknowns for my limited knowledge, are such effects known? Would there be an approved way-out for it?

PS I have checked https://support.mozilla.org/bm/questions/1412934 especially the message posted by lazizakhmedov1014, and do not see this to apply to me - short of a reinstall - FYI

When loading webpages, it will often take 60-90 seconds to load the page. I've only seen this happen when loading the page for the first time, once it loads navigating through subpages is seamless. It doesn't seem to be tied to any particular domain, I've had it happen randomly on gaming websites, tech websites, even google searches. The most notable coincidence is that in the networking tab of the developer console, it always(?) takes almost exactly 30 seconds on DNS resolution, 30 seconds on Connecting, sometimes a 30s Blocking element, and then the remainder is near instantaneous; screenshot attached. My network is fine, I'm able to play low-latency games without issue, and Chrome is not exhibiting the same behaviour.

Things I've tried to resolve:

• Restarting computer -- issue has been persisting for months
• Created a new Firefox profile -- still showing the same behaviour
• Disabling all addons/testing Troubleshoot Mode
• Proxy settings in Firefox -- No Proxy and System proxy settings are both showing the behaviour
• Disabling DNS over HTTPS

Any help would be greatly appreciated.

Hello Mozilla. I am logged on to my Firefox account on a new computer. Although I have logged in, I haven't experienced Firefox automatically syncing my bookmarks and extensions as I did two computers ago to this last computer. I have tried syncing numerous time (pressing the sync button in my account) to no avail. What do I need to do to get this working? Thank you for your time and attention.

why is it that ever since the FORCED update crap, i can no longer have ad blockers? why am i now FORCED to watch ads for videos as short as 1 minute 52 seconds?

WHAT THE HELL IS GOING ON WITH YOU GUYS AT MOZILLA? firefox USED TO BE something i would recommend to people but, now that i can no longer have facebook container, any ad blockers or anything else for privacy, i dont see no reason to recommend firefox any longer. if i have to continue waiting 10-15 minutes for a 5 minute video to load just so the ads can load first, and i can no longer have ANY privacy online, there is no need for me to continue using firefox because i can go through the EXACT SAME BULLCRAP USING google or internet explorer, i can have the SAME amount of time and bandwidth WASTED on ads as using google or internet explorer.

i got a message from you guys saying i HAD NO CHOICE but to update or not be able to use the internet, i tried, then you guys sent me the message that i can NOT update for windows 7 (even though your site said windows 7 CAN get the up to date firefox web browser) because my computer is TOO DAM OLD! WHY THE HELL DO YOU LIE TO PEOPLE LIKE THAT! NOT EVERYONE CAN AFFORD THE COST OF A NEW COMPUTER EVERY TIME WE TURN AROUND! ESPECIALLY US WHO ARE DISABLED AND ARE ON A FIXED INCOME!

IF I WANTED TO WATCH SO MANY ADS, I WOULD GET A SATELITE DISH AND WATCH THE PARAMOUNT NETWORK!

NO privacy while web browsing? so you guys are just letting facebook track me online now! what the hell?? not to mention 300 ADS instead of seeing what my friends post to face book or the pages i am following!

want me top stay with you guys for a web browser? then i need the ad blockers add-ons and privacy ad-ons back!

ps. word of mouth spreads pretty fast!

I am looking for an add on to assist in filing emails but I can't find anything at all. I used to have one which was quite good but can't now recall the name. Suggestions would be greatly appreciated:)

Hello,

When I log in the long used firefox account in my new computer, it shows to register a new account, and seem all the “Favorites” websites and saved password was lost. How to fix it? The old account is still on my cellphone and functional.

I don't what or how it happened.

But one night all I can remember was I updated my Firefox in Windows and my account was synced. I use to have all my browser history on my Macbook air. But suddenly the next day I discover that all of my history is gone. I have no idea what caused or how I can recover it again. I tried the internet and nothing helped me with my problem. So now I'm resorting to this and hopefully someone can tell me what to do.

Recently I've had the Un-welcome experience of Scripts triggered on YouTube, which Over-ride my Installed extensions to Firefox.

I've had YouTube, somehow Disable extensions and refresh the webpage... Without my concent or even an option for concent!

I've even blocked the popup window, which triggers the script which performs this action within another extension... and within 7-10 days Youtube has by passed the bypass that i've employed...

In my opinion a web-browser which allowes for extensions to be installed and run... should Block any and All scripts which try to disable extensions!

I seriously hope this can be looked into asap... or someone in the community has a work around, as my work around (blocking hte window which triggres the script, which disables the extension....) was by-passed within 7-10 days...

I used to think myself a compettent net user, but i'm aged out atm... still if i'm unable to prevent this sh*t and manipulation within FireFox, I doubt the average user or the layman will have a chance in hell of being secure and keeping their chosen extensions running...

This needs looking into ASAP!

Last week the bookmarks button to bring on the sidebar disappeared from my toolbar. Browser and OS up to date. In my attempt to add it back I now see it has also been eliminated from the Customize palette. What gives?

You guys are just too stupid. It's better not to update at all. Where did you update the recently closed tab restoration function and the drag-and-drop search function to?

For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".

OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.

Things I have tried:

Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open

Refresh Firefox to remove settings and addons No change

Uninstall Snap and try direct Apt package No change

Remove ~/.mozilla to fully remove any residual settings/cache/etc No change

Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!

I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.

The image I uploaded is all I am getting. I even got on line one on one with my McAfee and they got on my computer. I need help guys. Is not just browse, I am also having issues accessing the website I know my account has been compromise. All I did different is add 2 adds on that were recommended by Mozilla and I removed them but it looks like the damage was already done.
