Gmail has always operated in Firefox until about last week.
It will open into Explorer and Google Chrome.
I try to open gmail and the screen stays blank.
Computer literacy is not a strength!
You might have seen the advice to clear your cache and cookies, but didn't get the specific steps to do so. Here they are.
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
You also can clear Firefox's cache completely using:
orange Firefox button or Tools menu > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
This can take a few minutes to run if you have a large hard drive.
(2) Remove your google.com cookies
Save any pending work first, then, while viewing a page on google.com:
Select each cookie and click Remove. Then OK out and try reloading the page.
Can you log in and get to your mail?
a million thanks for the detailed attempt to help -
for some reason it did not do the trick
SO, still no gmail in FIREFOX
(and, I am so backward as to be having difficulty with instructions right here!)
If cached files and bad cookies are not causing the problem, the next culprit usually is an add-on. This article describes Safe Mode and related options for checking on that possibility: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems. Any luck?
