Hello: FF dev build 83.0b5 64bit, w10p. A new odd issue to me. Using ActBlue (political PAC) I sometimes use my regular credit card to make small political contribution. As of 28oct20, this FF stops completing the transaction. I hit the "donate" button, & nothing happens. I have seen a "processing" type msg from the vendor us. promptly - but again, the current page just sits there, the "processing"action & pg don't happen. On 28th eve, I checked my bank acct to see if somehow the donation had been made (I would see the deduction taken), and no, it hadn't. No prior nightly build type update had shown this behavior. I have no other FF on this w10 (no stable, nada anything else for FF). I have made no changes to extensions, plugins or otherwise. I had to go to stable chrome to complete the donation, and chrome did it right the 1st time. So, this is just an FYI, I don't know where else to post nor may I have the rights to post elsewhere. Tx.
