Firefox slowly loads, home page take too long to load- I can bring up chrome and manually log in and switch back firefox is still "loading site. Safe mode works great - very fast, disable antivirus-no change , re-installed Firefox with NO add ons or ext. still slow !! any suggestions, Chrome/ MS Edge work fast on same machine.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Is this about Firefox Troubleshoot Mode or about booting Windows in Safe Mose ?

Boot the computer in Windows Safe Mode with network support to see if that has effect.

In safe mode its very fast - in the working environment this is the only slow browser. How do I narrow down the conflict ? OR re-install without any previous settings or book marks ?? This just happened one day about 2 months ago

Did you mean Firefox Safe Mode?

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.
