Diễn đàn hỗ trợ Firefox

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 :)

When I start Firefox in the morning, I normally have multiples pages open, which I need for work. Over the course of the day, the websites become unreadable in terms of the fonts and even new pages I cannot see all of the fonts. I have attached a image from a new website I loaded and if you look above username and below log in you will see messed up fonts that are unreadable. They even print that way. I have to exit all pages and restart Firefox to make it go away. It is a pain to have to do that and re-log into all the sites I need open during the day. This has happened for about a year. I update it all the time and it never fixes it. I have a desktop computer. I have windows 11 professional. I have all updates to windows and all updates to programs in Microsoft Store. I have Firefox 152.0.6 (64-bit). I have reported this before but go not useful information from the report I put on here.

I have 2 different bookmarks. 1 for Citi Card Visa & ! for Citi Card MC. Both take me to the same online screen. Can "cookies" or something similar in Firefox be causing this and can I fix it. Citi Card techs can't help!

My version is the most recent, 152.0.6.

After a few minutes, text searches in the address bar unpredictably stop working. This might happen right away, or it may take a while. The result is always Secure Connection Failed The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Here are the problems that I encounter literally every day: Randomly unable to access GMail: account selection entry screen does not respond, or drop-down account selection when logged on does not respond. Randomly unable to access URLs embedded in emails. Browser locks up unpredictably. Videos in Facebook randomly fail to render: the audio plays, but the bottom half of screen completely blanks. Randomly unable to access websites in general: "secure connection failed". Randomly refuses to search for terms entered in the address bar, with "secure connection failed". Widgets on web pages randomly fail to respond.

I'm using the VPN that comes with my AV package, and turning it off makes everything work again. However, I'm certainly not going to turn off part of my web protection (which I am paying for) in order to get Firefox to perform basic browser capabilities. TBH, all of this started when Firefox started aggressively promoting their own VPN, so it's quite tempting to put two and two together.

I would prefer not to resort to Edge or Chrome, but at this point I don't see an alternative as they do not have these problems and Firefox has basically become unusable.

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.

Using Windows 11 on Lenovo laptop, Firefox 152.0.5

1. I go to X.com and am presented with the logon screen and the option to logon using Email or Username, Phone, Google and Apple.

2. Try entering my email address in the logon screen and get a red ! error: "Please enter a username, email, or phone number."

3. Try entering my username in the logon screen and get a red ! error: "Please enter a username, email, or phone number."

4. Try using the Google option and it performs as if I was logged in but the system never leaves the logon screen.

5. Try using the Phone option and enter my phone number and get a red ! error: "Something went wrong. Please try again."

6. Delete all history, cookies, etc. Restart Firefox. Same issues as above.

7. I disable all Extensions and restart Firefox. Same issues as above.

8. I try a Private window and am able to log in just fine.

I am at a loss here on how to proceed. This is happening on two individual systems in my home both running the same version of Firefox.

I have Brave set as default search engine. I type in the address bar, hit enter, and always get a Brave screen with "404 Nothing matches the given URI". I downloaded the Brave browser and the problem goes away. But I prefer Firefox as my browser, so I'm hoping there is an easy fix to this.

Trying to watch a video on Nebula and it will not load. Receiving the following errors:

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 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

                                                                                  the new view with the email control tabs to the left and not all show is the right shreen shot or bottom screen shot

Hi support and team,

I am seeking for your help, I look for the extension "ShopBack" which help me to track the online purchases, cashback / rewards.

However, I cannot search and install after I have remove it for some troubleshoot.

Looking forward to hearing from you soon. Hope I can get it installed and continue to enjoy the benefit.

Regards, Kong
