About 1 week ago, Firefox started to randomly and suddenly shut down.
It typically happens once, max twice a day and when it happens, it closes all open tabs without giving any warning and without showing any error or crash report. The shut down is triggered by a click, typically a click to open a link, or open a new tab - that is, it does not shut down by itself.
Firefox does not reopen by itself, you must reopen it. When it reopens, it goes back to the latest situation prior to the shut down event, ie, it reopens all closed tabs and the closed web links - as if it were a crash.
I did not find any particular pattern (ie, websites, time of the day, open apps, amount of time online, etc) - it appears rather random.
No other issues reported - slow system, unwanted downloads, opening unwanted links, etc
EVENTS HAPPENED RECENTLY THAT MAY BE RELATED
1. My AV Provider (Bitdefender) sent me a message saying that it is about to stop supporting my OS (Win XP)
2. Yesterday another one of my AV shields (Malwarebytes Antiexploit) reported that an exploit code was blocked in Firefox, but without giving more details
3. Yesterday morning my PC asked me to log in by clicking on my user name. The thing is, I have never activated this option, as the PC is set to go directly onto the desktop, without asking to click on usernames, or typing passwords.
After yesterday, it did not do it again.
WHAT I HAVE DONE
- Run a full scan with Malwarebytes Antimalware - no issues found
- Checked if all the installed plugins were up to date - no issues found
- Opened Firefox in safe-mode - currently checking if the issue persists
- Checked the Firefox crash log - no crash reported
OVERVIEW OF MY SYSTEM AND APPS
- OS: Win XP SP3 32 Bit. Updates are still coming, mostly for MS Apps (Excel, Word, etc)
- Browser: Firefox 52.3.0 32 Bit
- AV running in the backgound: Bitdefender Free 1.0.21.1109 updated today; Malwarebytes Anti-Exploit Beta 1.10.1.24 updated
- AV on-demand: Malwarebytes Anti-Malware Free 2.2.1.1043 updated
- Plugins: as per list below
I initially suspected an exploit/ malware, but did not find an evidence as of now.
Course of action suggested?
Thanks.
