Diễn đàn hỗ trợ Firefox

Starting yesterday firefox, no recent updates etc, gives a 403 error for several large corporate sites and 404 page not found for most paypal payment pages. These sites/pages work fine with Chrome. There were no changes by by myself to my firefox installation, not any antivirus changes.

Within the last hour today everything is working properly. What is going on? jn

Dear Mozilla:

It is SAD that the OS I have will no longer be supported due to exploits.

Considering the # of exploits, backdoors, poor coding, etc., in the later Windows OS versions - 1 would truly think that supporting the older and MUCH more secure Windows OS's would be wise.

Yes, they have "holes", but overall much fewer than current OS's.

Plus, the bad actors are very busy exploiting 10 & 11 and pretty much have ignored the prior versions.

Question... what if a major exploit is found that affects all OS's from 11 down to unsupported?

Will Mozilla make sure to supply a patch to the unsupported due to the danger of the new & serious "hole" found?

I vote... it would be wise to maintain a small contingency of legacy developers to help those who cannot buy new systems or flat out HATE the UI & UX of the 10 & 11.

Makes sense?

How can I troubleshoot and resolve common issues with my Mozilla Firefox browser using the resources available on the Mozilla Support website?"

When I went to start firefox today on my MS Windows computer, I got a file error message saying pathway was corrupted (or something like that) and then the firefox app disappeared from my pinned toolbar. When I went and reinstalled it, all of my saved bookmarks and passwords were gone. How do I get them back?
