Firefox supportforum

Hi can somebody help me please? Sitting here on Christmas Eve at work trying to fix Firefox.

In a nutshell I have a really really annoying bug with Firefox which is going to cause me to pull all my hair out.

In the past the program used to check for updates and it used to work fine during this procedure.

Lately though I've been experiencing a really strange bug.

Whenever Firefox checks for updates the browser then cannot load a single webpage or anything while it is checking. Sometimes the checks can take around 3-5 minutes to complete.

Any videos or streams come to an eventual halt.

I have tried tweak a few settings in about:config such as app.update.interval

I have tried uninstalling and re-installing the browser - No change. This still happens usually about 5-8 times a day.

This computer is used for medical emergencies for our clients. We need a full functioning browser. I thought Firefox was that browser but I am beginning to think about installing something else now.

In these situations lives could be put at risk and I want to remedy this problem now before the new year. I imagine we will have a lot of patients coming in. I need to quickly submit forms at times and I really need a stable browser.

a) Can I turn off updates? I would prefer to check manually for updates once a week or so via Help -> About b) Can I reduce the frequency of the checks for updates? c) Is this going to be a normal feature for Firefox from now on?

My C:\Users\<username>\AppData\Local\Temp folder fills up with Firefox update folders called "MozillaBackgroundTask{numberletterstring}", a new one of which appears every 7 hours (except when computer is off because I changed the Update setting after this issue started so the "Allow Firefox to automatically install updates" has the "when Firefox is not running" unchecked). Every day I delete the previous day's folders. This is annoying. It started within the last month. I don't use Firefox as my default browser. This only happens on my Windows 7 Pro laptop, not on my Windows 10 laptop. Can anyone tell me why this has started happening and how to stop these files keep accumulating please?
