Firefox Community Forum

This is a recent problem but when I try to open new tabs they don't load or take a very long time to load. I wind up shutting down my computer and resarting but sometimes that doesn't help. it seems to be getting worse. I do not use any other VPN but yours and Duckduckgo to search. I use a macbook air. Any suggestions? Thanks

Hi Moz Support,

I've had this happen several times before, but this time it really annoyed me.

I sent tabs from one Firefox instance to another on another device. I closed these tabs on the source device. These tabs were quite old this time, I'd not opened them in a while - this becomes important later.

On the destination device, let's call it "madbilly's destination Firefox", these tabs didn't arrive. After doing a couple of tests where I sent a tab from my mobile to this instance, I realised that this was a similar problem to what I'd had before, which is one where a Firefox instance/profile for some reasons "resets" itself and it seems to create a new instance in Firefox Sync. Tabs which have previously been sent to "madbilly's destination Firefox" don't arrive, because (I think) it's not registered in Firefox Sync as the same instance. These sent tabs, if closed on the source instance (which I did) are lost, unless one reopens the source instance and Ctrl-Shift+T reopens closed tabs. Unfortunately, in this case because the tabs were old and I hadn't opened them for a while there was no way to do this, because Firefox doesn't remember closed tabs which are not stored in memory (another bug, any fix?), except for looking in old session store backups which I'm going to do after I write this post, though I don't know if that will work.

Also, on Android, because it only remembers 10 closed tabs it's not really feasible to retrieve lost sent tabs this way either, and as there's no access to the session store backups the tabs are definitely lost.

Oddly, when this happens "madbilly's destination Firefox" usually appears twice in the send-tab-to menu, but in this case it didn't. To be able to send to this instance I had to sign out of Firefox sync on this instance and sign in again. Then the same instance appeared twice in the sync menu, the old one being now unreachable.

I'd like to know: 1. Why does this happen? 2. How to avoid it happening? 3. Is there a bug registered about this? 4. When will it be fixed and prevented from happening again.

I generally find that this happens when a Firefox instance isn't shut down properly, which on my old desktop I put down to it running out of resources, but on this shiny new laptop from work that doesn't make sense.

All help much appreciated thanks :)

With the latest updates, my Firefox window has no way to minimize/resize/close the window. (There are also no tabs/bookmarks) I see nothing in the settings options that seems relevant.

Just made a new profile and wiped everything from my history following another issue which isn't strictly speaking resolved. I am unable to load image-dense websites with any consistency. Issues do not occur on other browsers. I receive similar errors on Twitch:

I'm using Windows 10 on a PC. Norton Security app is preventing web browsing by Firefox. The message I get is: "We prevented your connection to ful.hartonly.com because it is a dangerous webpage. Threat category: URL:Blacklist" I can still web browse using Google Chrome without any problem. What is ful.hartonly.com and how do I clear it?

I have always accessed my LinkedIn account on Firefox. Suddenly today, my PW does not work, and my email address for PW reset does not return a PW reset link. Cleared cache without success. I can access LinkedIn on Chrome. Can you suggest what I have done to my Firefox to cause this? Thanks!

hello! this may not be an emergency, but im still curious. will the sports widget be updated after the world cup? i think this would be cool if after the world cup people could choose a sports they want to follow (tennis, soccer, formula-1, etc.) and the widgets will show the updates of the following sport. what will be after the world cup ends?

i have been using the old yahoo for years and now it seems they changed the layout to resemble google. it sucks. if i wanted googles layout i would use my google email. if i use this term https://mail.yahoo.com/d/settings/1 i get the old yahoo setup screen and then i have to click return to mail and the old screen stays until i either restart the pc or restart fire fox. i do not see in fire fox setting an area that lets me put in a startup term like chrome has that will restart yahoo in the view i like. being that view is still there.

the old view that i like with the blue on both sides
