I have used Firefox for email, web browsing etc for many years without issue, until about 2 weeks ago. I was using gmail to send an email and a small attachment would not fully upload (locking up at 75%). I looked at gmail help and the recommendation was to flush cookies and cache. I did this and have had problems ever since. GMail: Connecting to gmail is a hit or miss affair - it mostly does not work at all but on rare occasions it does connect. If it does load it is very slow, often I cannot change tabs or access labels. I cannot switch inboxes to other accounts. I mostly cannot send emails (though very occasionally I can). When trying to switch accounts it mostly just says something went wrong but once or twice it has brought up the list of accounts but I cannot select one. I can rarely send an email - it is very slow, it says working but mostly nothing happens. Sometimes an Oops 01 error message appears. I have not been able to attach a file to any email I have tried to send. I am seem to be receiving emails without issue. [Gmail mostly works on Chrome but sometimes I have trouble sending]. Google Search: When I use Google as a search engine I often get only a white screen but it will sometimes bring up a screen of search results however when I click on the link either nothing happens or it is really slow to load the page - once the page loads navigating around the site is normal. I have no issues when using Duck Duck Go or if I type the address into the address bar or it is a book marked site. YouTube: I can rarely connect to Youtube using Firefox - it mostly just sits at a white screen with the address in the address bar but nothing happening. If it does connect it is incredibly slow at searching or changing screens. I often get a message saying I am not connected to the internet but I am because I have other things open and operating. Google docs: I cannot access google docs using Firefox but can using Chrome. I have no issues with online gaming or streaming sites. It seems to be only google related services that are giving me grief.
