I associated .pdf to be opened with Firefox instead of a dedicated pdf reader since I installed the addon, but out of curiosity I disabled the addon and opened a pdf file from a local drive through Firefox directory browsing and I experienced tabs constantly being gushed open without a second delay. It would not end until I quit Firefox.
